Re: Solr Auto-Complete

[Alexandre Rafalovitch]

For suffix matches, you copy text the field and in the different type add
string reversal for both index and query portions. So you are doing prefix
matching algorithm but on reversed strings.

I can dig up an example if it is not clear.

Re: Solr Auto-Complete

[Andrea Gazzarini]

Do you mean "phrase" or "term" prefixes? If you try to put a field value
(two or more terms) in the analysis page you will see what the index
analyzer chain (of my example field type) is doing. The whole value is
managed as a single-ngrammed token, so you will get only a phrase prefix
search, as in your request.

If you want to manage also terms prefixes, I would also index another field
(similar to the example you posted); then, the search handler with
e(dismax) would have something like this:

   
>
text_suggestion_phrase_prefix_search^b1
text_suggestion_terms_prefix_search^b2




b1 and b2 values strictly depend on your search logic.

Is that close that what you were looking for?

Best,
Andrea

Re: Solr Auto-Complete

[Salman Ansari]

Hi,



I have updated my schema.xml as mentioned in the previous posts using

















This does the auto-complete, but it does it at every portion of the text
(not just at the beginning) (prefix). So searching for "And" in my field
for locations returns both of the following documents.





1

AD

*And*orra

أندورا

1519794717684924416





5

AG

Antigua *and* Barbuda

أنتيجوا وبربودا

1519794717701701633





I have read about this and at first I thought I need to add side="front"
but after adding that, Solr returned an error (when creating a collection)
indicating "Unknown parameters 

Re: Solr Auto-Complete

[Andrea Gazzarini]

Hi Salman,
that's because you're using a StandardTokenizer. Try with something like
this (copied, pasted and changed using my phone so probably with a lot of
mistakes ;) but you should be able to get what I mean). BTW I don't know if
that's the case but I would also put a MappingCharFilterFactory

Re: Solr Auto-Complete

[Salman Ansari]

Thanks a lot Andrea. It did work.

However, just for my understanding, can you please explain more how did you
make it work for prefixes. I know you mentioned using another Tokenizer but
for example, if I want to tweak it later on to work on suffixes or within
phrases how should I go about that?

Thanks again for your help.

Salman

Re: Solr Auto-Complete

[Salman Ansari]

That is right. I am actually looking for phrase prefixes not each term
prefix within the phrase. That satisfies my requirements. However, my
additional question was how do I manipulate the filedType to later allow
for suffix matches as well? or will that be a completely different
fieldType definition?

Salman

Re: Solr Auto-Complete

[Alexandre Rafalovitch]

You can see an example of similar use at:
http://www.solr-start.com/javadoc/solr-lucene/index.html (search box).

The corresponding schema is here:
https://github.com/arafalov/Solr-Javadoc/blob/master/JavadocIndex/JavadocCollection/conf/schema.xml#L24
. It does have some extra special-case stuff to allow to search by the
fragments, but the general use case is the same.

   Alex.

Re: Solr Auto-Complete

[Salman Ansari]

Thanks Alan, Alessandaro and Andrea for your great explanations. I will
follow the path of adding edge ngrams to the field type for my use case.

Re: Solr Auto-Complete

[Alessandro Benedetti]

"Sounds good but I heard "/suggest" component is the recommended way of
doing auto-complete"

This sounds fantastic :)
We "heard" that as well, we know what the suggest component does.
The point is that you would like to retrieve the suggestions + some
consistent payload in different fields.
Current suggest component offers some effort in providing a payload, but
almost all the suggester implementation are based on an FST approach which
aim to be as fast and memory efficient as possible.
Honestly you could experiment and even contribute a customisation if you
want to add a new feature to the suggest component able to return complex
payloads together with the suggestions.
Apart that, it strictly depends of how you want to provide the
autocompletion, there are plenty of different lookups implementation and
plenty of tokenizer/token filters to combine .
So I would confirm what we already said and that Andrea confirmed.

If anyone has played with the suggester suggestions payload, his feedback
is welcome!

Cheers

Re: Solr Auto-Complete

[Salman Ansari]

Sounds good but I heard "/suggest" component is the recommended way of
doing auto-complete in the new versions of Solr. Something along the lines
of this article
https://cwiki.apache.org/confluence/display/solr/Suggester


  
mySuggester
FuzzyLookupFactory
DocumentDictionaryFactory
cat
price
string
false
  


Can someone confirm this?

Salman

Re: Solr Auto-Complete

[Andrea Gazzarini]

Hi Salman,
few months ago I have been involved in a project similar to map.geoadmin.ch
and there, I had your same need (I also sent an email to this list).

>From my side I can furtherly confirm what Alan and Alessandro already
explained, I followed that approach.

IMHO, that is the "recommended way" if the component's features meet your
needs (i.e. do not reinvent the wheel) but it seems you're out of those
bounds.

Best,
Andrea

Solr Auto-Complete

[Salman Ansari]

Hi,

I am looking for auto-complete in Solr but on top of just auto complete I
want as well to return the data completely (not just suggestions), so I
want to get back the ids, and other fields in the whole document. I tried
the following 2 approaches but each had issues

1) Used the /suggest component but that returns a very specific format
which looks like I cannot customize. I want to return the whole document
that has a matching field and not only the suggestion list. So for example,
if I write "hard" it returns the results in a specific format as follows

  hard drive
hard disk

 Is there a way to get back additional fields with suggestions?

2) Tried the normal /select component but that does not do auto-complete on
portion of the word. So, for example, if I write the query as "bara" it
DOES NOT return "barack obama". Any suggestions how to solve this?


Regards,
Salman

Hi Salman,

It sounds as though you want to do a normal search against a special 'suggest' 
field, that's been indexed with edge ngrams.

Hi Salman,
I agree with Alan.
Just configure your schema with the proper analysers .
For the field you want to use for suggestions you are likely to need simply
this fieldType :













This is a very sample example, please adapt it to your use case.

Cheers
