Please note: here we have autosuggestion with `SpellCheckComponent`, which
we want to filter.

Filter the Solr autosuggestion in Hybris

[Ankit Patel]

I am trying to implement Solr context filtering to filter auto-suggestion
result based on the category value.

*schema.xml*





























*solrConfig.xml*


categorydic
org.apache.solr.spelling.suggest.Suggester
org.apache.solr.spelling.suggest.fst.AnalyzingInfixLookupFactory
org.apache.solr.spelling.suggest.DocumentDictionaryFactory
autosuggest_en
allCategories_string_mv
false
false
text_spell_en
${solr.core.dataDir}/suggesttest


fields look like

"spellcheck_en": [
  "ANKITHI LIMIT",
  "ROU7000272",
]

"allCategories_string_mv": [
  "3m",
  "harddiskcategory",
  ]


http://localhost:8983/solr/master_Product/suggest?spellcheck=true=true=categorydic=json=mytest=harddiskcategory

When I am hitting this URL with spellcheck.dictionary=categorydic,
spellcheck.cfq=harddiskcategory,spellcheck.q=mytest it won't filter the
result. I am getting all the match of *mytest*

Solr Version: 5.3.0
Hybris Vesion: 6.0

Any clue?

We see that the index that is built for auto-suggestions is not propagated to

Need auto suggestions indices to propagate to all the solr instances 
automatically.
So, request for suggestions/solutions for the same.

Re: Using Context field unable to get autosuggestion for zip code having '-'.

[Alessandro Benedetti]

With that configuration you want to auto suggest Office names filtering them
by zip code.

Not sure why you perform an ngram analysis though.
How do you want to filter by zip code ? Exact Search ? Edge ngram ?

Using Context field unable to get autosuggestion for zip code having '-'.

[Nareshkumar P]

Hi Team,


Problem: Unable to get autosuggestion for zip code having '-'.

We are using the context field as part of autosuggestion search.
when we try with context search, we are not getting results for zip code having 
'-', ex:"92240-3064".
Hence we did following the change in manager-schema and solrConfig

In Managed-scheme this changes we are added.


  



  


  

Created copy field for Zip code in managed-scheme
  
  

Added this line for suggester in solrconfig.xml
 zip-autosuggest

 sample example:

 
  OfficeName
  officeName
  practiceLocationNumber
 zip-autosuggest
  AnalyzingInfixLookupFactory
  officeName_suggester_infix_dir
  DocumentDictionaryFactory
  practiceLocationNumber
  lowercase
  officeName_provider_suggestor_dictionary
  string
 

we ran the reindexing without reloaded data. we are not getting the suggestion 
for zip code having "-".

can you please suggest the solution for it.


Thanks

Nareshkumar

Re: Autosuggestion

[OTH]

Hello
So, from what I've picked up so far:
FST only matches from the beginning of the input, but can handle spelling
errors and do stemming.
AnalyzingInfix can't handle spelling errors or stemming but can match from
the middle of the string.
(Is there anyway to achieve both of the functionalities above, if need be?)
Performance-wise, FST's are faster and more compact?

Thanks

Re: Autosuggestion

[Erick Erickson]

bq:  FST-based vs AnalyzingInfix

They are two totally different things. FST-based suggesters are very
fast and compact. But they only match from the beginning of the input.

AnalyzingInfix creates a "sidecar" index that's searched like a normal
index and the _field_ is returned. Thus analyzinginfix can suggest
"my dog has fleas" when entering "fleas", but the FST-based suggesters cannot.

Best,
Erick

Re: How to implement Autosuggestion

[chandan khatri]

Hi Alessandro,

Thanks for replying!

Here are my answers inline.

1. "First of all, simple string autosuggestion or document autosuggestion ?
(
with more additional field to show then the label)


 Document autosuggestions
2. Are you interested in the analysis for the text to suggest ? Fuzzy
suggestions ? exact "beginning of the phrase" suggestions ? infix
suggestions ?"

--- I am interested in analysis for the text to suggest.

3. In the case you want to show the label AND the category AND whatever ( in
Amazon style to make it simple) .
A very straighforward solution is to model a specific Solr Field for your
product collection.
This field will contain the name of the product, analyzed according your
need.
Then your autosuggester will simply hit that field on each char typed, and
you can show the entire document in the suggestions ( with all the fields
you want) .

 Not sure what you mean by indexing a field with the name of product
analyzed according to my need? Can you please give an example?

Thanks again for taking time to respond to my query.

Re: How to implement Autosuggestion

[Alessandro Benedetti]

Hi Chandan,
I will answer as my previous answer to a similar topic that got lost :
"First of all, simple string autosuggestion or document autosuggestion ? (
with more additional field to show then the label)
Are you interested in the analysis for the text to suggest ? Fuzzy
suggestions ? exact "beginning of the phrase" suggestions ? infix
suggestions ?"

If you need only the category *payloadField* should be what you need .
I never used it as a feature but it is there [1] .
As Reth suggested, at the moment Solr supports only one payloadField,
ignoring the others ( code confirms this).

In the case you want to show the label AND the category AND whatever ( in
Amazon style to make it simple) .
A very straighforward solution is to model a specific Solr Field for your
product collection.
This field will contain the name of the product, analyzed according your
need.
Then your autosuggester will simply hit that field on each char typed, and
you can show the entire document in the suggestions ( with all the fields
you want) .
Or we take a look to the implementation and we contribute the support for
multiple *payloadField*.

Cheers

There is a payload attribute but I'm not sure if this can be used for such
use case. Lets wait for others contributors to confirm.

If its just a category that you need then the work around(although not
accurate one) that I can think of is to include the category value to the
same field with pipe separation and extract from it?

How to implement Autosuggestion

[chandan khatri]

Hi All,

I've a query regarding autosuggestion. My use case is as below:

1. User enters product name (say Nokia)
2. I want suggestions along with the category with which the product
belongs. (e.g Nokia belongs to "electronics" and "mobile" category) so I
want suggestion like Nokia in electronics and Nokia in mobile.

I am able to get the suggestions using the OOTB AnalyzingInFixSuggester but
not sure how I can get the category along with the suggestion(can this
category be considered as facet of the suggestion??)

Any help/pointer is highly appreciated.

Thanks,
Chandan

Re: How to implement Autosuggestion

Hi All,

I've similar query regarding autosuggestion. My use case is as below:

1. User enters product name (say Nokia)
2. I want suggestions along with the category with which the product
belongs. (e.g Nokia belongs to "electronics" and "mobile" category) so I
want suggestion like Nokia in electronics and Nokia in mobile.

I am able to get the suggestions using the OOTB AnalyzingInFixSuggester but
not sure how I can get the category along with the suggestion (can this
category be considered as facet of the suggestion??)

Any help/pointer is highly appreciated.

Thanks,
Chandan

Re: How to implement Autosuggestion

[Alessandro Benedetti]

Hi Mugeesh, autocompletion world is not that simple as you would expect.
Which kind of auto suggestion are you interested in ?

First of all, simple string autosuggestion or document autosuggestion ? (
with more additional field to show then the label)
Are you interested in the analysis for the text to suggest ? Fuzzy
suggestions ? exact "beginning of the phrase" suggestions ? infix
suggestions ?
Try to give some example and we could help better .
There is a specific suggester component, so it is likely to be useful to
you, but let's try to discover more.

Cheers

How to implement Autosuggestion

[Mugeesh Husain]

Hi,

I am looking for the best way to implement autosuggestion in ecommerce 
using solr or elasticsearch.

I guess using ngram analyzer is not a good way if data is big.


Please suggest me any link or your opinion ?



Thanks
Mugeesh

Re: Different options for autocomplete/autosuggestion

[Kai Schlamp-2]

One autosuggestion solution would be to query normal text fields. That way
you have the whole feature set of Solr (like NGram filtered text for infix
search or field queries to scope the search). If you also store the data of
the text field you directly have the results to use as autosuggestions.
Unfortunately in some applications (like ours) different documents often
contain the same data for the same field.
So this approach may return many duplications as search hits for exactly
this field. If one could collapse the results by that field all duplications
would be gone and you only distinct hits remain (what one would expect from
autosuggestions). At least this is how I understood field collapsing.

RE: Different options for autocomplete/autosuggestion

[Robert Petersen]

I take raw user search term data, 'collapse' it into a form where I have
only unique terms, per store, ordered by frequency of searches over some
time period.  The suggestions are then grouped and presented with store
breakouts.  That sounds kind of like what this page is talking about
here, but I could be using the wrong terminology:

 @Robert: That sounds interesting and very flexible, but also like a

 directly by  using Ajax ... one of the big benefits in my opinion when
 using  Solr.
 @Bill: There are some things I don't like about the  Suggester
 component. It doesn't seem to allow infix searches (at least it is
not
 mentioned in the Wiki or elsewhere). It also uses a separate  index
 that has to be rebuild independently of the main index. And it
doesn't
 support any filter queries.
 
 The Lucid Imagination blog also  describes a further autosuggest
 approach 
(http://www.lucidimagination.com/blog/2009/09/08/auto-suggest-from-popu

 The  disadvantage here is that the source documents must have distinct
 fields  (resp. the dih selects must provide distinct data). Otherwise
 duplications  would come up in the Solr query result, cause of the
 document nature of  Solr.
 
 In my opinion field collapsing seems to be most promising for a  full
 featured autosuggestion solution. Unfortunately it is not  available
 for Solr 1.4.x or 3.x (I tried patching those branches several  times
 without success).

RE: Different options for autocomplete/autosuggestion

[Robert Petersen]

I like field collapsing because that way my suggestions gives phrase
results (ie the suggestion starts with what the user has typed so far)
and thus I limit suggestions to be in the order of the words typed.  I
think that looks better for our retail oriented site.  I populate the
index with previous user queries.  I just put wildcards on the end of
the collapsed version what the user has typed so far.  It is very fast.
I make suggestions for every keystroke as a user types in his query on
our site.  Hope that helps.

Re: Different options for autocomplete/autosuggestion

Robert, thanks for your answer. What Solr version do you use? 4.0?
As mentioned in my other post here I tried to patch 1.4 for using
field collapsing, but couldn't get it to work (compiled fine, but
collapsed parameters seems to be completely ignored).

RE: Different options for autocomplete/autosuggestion

[Robert Petersen]

I am doing this very differently.  We are on solr 1.4.0 and I accomplish the 
collapsing in my wrapper layer.  I have written a layer of code around SOLR, an 
indexer on one end and a search service wrapping solrs on the other end.  I 
manually collapse the field in my code. I keep both a collapsed and uncollapsed 
version of the phrase in my index, the uncollapsed is the only one stored for 
retrieval btw.  I do this on both ends so I have complete control here...  
works well!   Different than a patch of course tho.

Robert, thanks for your answer. What Solr version do you use? 4.0?
As mentioned in my other post here I tried to patch 1.4 for using
field collapsing, but couldn't get it to work (compiled fine, but
collapsed parameters seems to be completely ignored).

2011/3/14 Robert Petersen rober...@buy.com:
 I like field collapsing because that way my suggestions gives phrase
 results (ie the suggestion starts with what the user has typed so far)
 and thus I limit suggestions to be in the order of the words typed.  I
 think that looks better for our retail oriented site.  I populate the
 index with previous user queries.  I just put wildcards on the end of
 the collapsed version what the user has typed so far.  It is very fast.
 I make suggestions for every keystroke as a user types in his query on
 our site.  Hope that helps.

 Hi.

 There seems to be several options for implementing an
 autocomplete/autosuggestions feature with Solr. I am trying to
 summarize those possibilities together with their advantages and
 disadvantages. It would be really nice to read some of your opinions.

 * Using N-Gram filter + text field query
 + available in stable 1.4.x
 + results can be boosted
 + sorted by best matches
 - may return duplicate results

 * Facets
 + available in stable 1.4.x
 + no duplicate entries
 - sorted by count
 - may need an extra N-Gram field for infix queries

 * Terms
 + available in stable 1.4.x
 + infix query by using regex in 3.x
 - only prefix query in 1.4.x
 - regexp may be slow (just a guess)

 * Suggestions
 ? Did not try that yet. Does it allow infix queries?

 * Field Collapsing
 + no duplications
 - only available in 4.x branch
 ? Does it work together with highlighting? That would be a big plus.

 What are your experiences regarding autocomplete/autosuggestion with
 Solr? Any additions, suggestions or corrections? What do you prefer?

RE: Different options for autocomplete/autosuggestion

[Robert Petersen]

Note that due to the 'raw' nature of my source data I also have to heavily 
filter my data before collapsing it also.  I don't want to suggest garbage 
phrases just because a lot of people searched on them.  We store auxiliary data 
in the index for filtering on to perform the grouping.

See how Lucid Enterprise does it... A bit differently.

Re: Different options for autocomplete/autosuggestion

[Kai Schlamp]

@Robert: That sounds interesting and very flexible, but also like a
lot of work. This approach also doesn't seem to allow querying Solr
directly by using Ajax ... one of the big benefits in my opinion when
using Solr.
@Bill: There are some things I don't like about the Suggester
component. It doesn't seem to allow infix searches (at least it is not
mentioned in the Wiki or elsewhere). It also uses a separate index
that has to be rebuild independently of the main index. And it doesn't
support any filter queries.

The Lucid Imagination blog also describes a further autosuggest
approach 
(http://www.lucidimagination.com/blog/2009/09/08/auto-suggest-from-popular-queries-using-edgengrams/).
The disadvantage here is that the source documents must have distinct
fields (resp. the dih selects must provide distinct data). Otherwise
duplications would come up in the Solr query result, cause of the
document nature of Solr.

In my opinion field collapsing seems to be most promising for a full
featured autosuggestion solution. Unfortunately it is not available
for Solr 1.4.x or 3.x (I tried patching those branches several times
without success).
