Good Open Source Front End for Solr

[Java Developer]

Hi,

What is the best open source front-end for Solr

Thanks

Portable Solr

[Java Developer]

Hi,

Like portable embedded web server (Spring Boot or Takes Or Rapid) Takes (
https://github.com/yegor256/takes) or Undertow (http://undertow.io/) or
Rapidoid (https://www.rapidoid.org/)

Do we have portable Solr server? Want to build an Web application with Solr
with portability?

The user needs should have only javaRest is portable...

Please advise.

Thanks

Re: Indexing word with plus sign

[Fundera Developer]

Thank you very much Erick!  You're right!

The "Char" part in PatternReplaceCharFilterFactory misguided me and I tought it 
was just for Char replacements. One I have gone through the documentation of 
CharFilters (my fault...) I realized that I could use the very same regex I was 
using with the PatternReplaceFilterFactory to replace the whole "i+d" 
expression, and nothing more than that, and it is working like charm now.

Thanks again!!

You need to distinguish between

PatternReplaceCharFilterFactory

and

PatternReplaceFilterFactory

The first one is applied to the entire input _before_ tokenization.
The second is applied _after_ tokenization to individual tokens, by
that time it's too late.

It's an easy thing to miss.

And at query time you'll have to be careful to keep the + sign from
being interpreted as an operator.
Best,
Erick

Are there any other approaches I could be missing?

Fundera,
You need a regex which matches a '+' with non-blank chars before and after. It 
should not replace a  '+' preceded by white space, that is important in Solr. 
This is not a perfect solution, but might improve matters for you.

remove '+' chars that are added by the user to identify compulsory

Hi,


Before applying tokenizer, you can replace your special symbols with

Spanish it is usual to find the term 'i+d'. We are working with Solr
5.5,
and StandardTokenizer splits 'i' and 'd' and sometimes, as we have in
the
index documents both in Spanish and Catalan, and in Catalan it is
frequent
to find 'i' as a word, when a user searches for 'i+d' it gets Catalan
documents as results.

I have tried to use the SynonymFilter, with something like:

i+d => investigacionYdesarrollo

But it does not seem to change anything.

Is there a way I could set an exception to the Tokenizer so that it
does
not split this word?

Thanks in advance!

Thanks Walter!!

For the sake of curiosity, do you remember which Tokenizer were you using in 
that case?

Thanks!

Years ago at Netflix, I had to deal with a DVD from a band named “+/-“. I gave 
up and translated that to “plusminus” at index and query time.

http://plusmin.us/ <http://plusmin.us/><http://plusmin.us/>

Luckily, “.hack//Sign” and other related dot-hack anime matched if I just 
deleted all the punctuation. And everyone searched for "[•REC]²” as “rec2”. The 
middot is supposed to be red. Movie studios are clueless about searchable

Get number of results in filtered query

[Fundera Developer]

Hi all,

we are developing a search engine in which all the possible results have 
one or more countries associated. If, apart from writing the query, the 
user selects a country, we use a filterquery to restrict the results to 
those that match the query and are associated to that country. Nothing 
spectacular so far  :-D


However, we would like to show the number of results that are returned 
by the unfiltered query, since we already have the number of results 
associated to each country as we are also faceting on that field. Is it 
possible to have that number without executing the query twice?


Thanks in advance!

Re: Problem building fuzzy suggestions

  true

  


However, to be honest, I still have no idea why this time it worked and 
the others did not. In order to learn for the next time, any 
clarifications would be highly appreciated.

Re: Problem building fuzzy suggestions

[Fundera Developer]

Following on this, I have been able to make Solr load correctly by 
replacing the line in the solrconfig.xml:


   JaspellLookupFactory


with the fully qualified class name:

   org.apache.solr.spelling.suggest.jaspell.JaspellLookupFactory


and now I can, as I said, start Solr, build the suggestions and run 
them. However, I am still getting nothing "fuzzy". If I query with 
"managem", I get several suggestions ("management" among them), but 
trying with "managm" or "manahem" does not provide any suggestions, even 
if I configure the accuracy parameter as low as 0.5 (and reindex, of 
course).


Am I doing something wrong? Is there any better alternative to getting 
fuzzy suggestions?


Thanks in advance!!

Re: Solr Autosuggest - Strange issue with leading numbers in query

[Developer]

Hi Erik,

Thanks a lot for your reply.

I expect it to return zero suggestions since the suggested keyword doesnt
actually start with numbers.

Expected results 
Searching for ga - returns galaxy 
Searching for gal - returns galaxy
Searching for 12321312321312ga - should not return any suggestion since
there is no keyword (combination) exists in the index.

Thanks

Hi,

I am trying to figure out a way to use multiple elevate.xml using the query

We have a scenario where we need to elevate documents based on

*
For authenticated customers

elevate documents based on elevate1.xml

*For non-authenticated customers*

elevate documents based on elevate2.xml

I am not sure if there is a way to implement this using any other method.

Hi,

I have a fieldtype as below configured to index the autocomplete phrase.

SOLR Security - Displaying endpoints to public

[Developer]

Hi,

We are currently showing the SOLR endpoints to the public when using our
application (public users would be able to view the SOLR endpoints (/select)
and the query in debugging console).

I am trying to figure out if there is any security threat in terms of
displaying the endpoints directly in internet. We have disabled the update
handler in production so I assume writes / updates are not possible. 

The below URL mentions a point 'Solr does not concern itself with security
either at the document level or the communication level. It is strongly
recommended that the application server containing Solr be firewalled such
the only clients with access to Solr are your own.'

Is the above statement true even if we just display the read-only endpoints
to the public users? Can someone please advise?

question regarding dismax query results

[Vulcanoid Developer]

Hi,

I have a solr schema which has fields related to Indian legal judgments and
want to provide a search engine on top of them.  I came across a problem
which I thought I would take the group's advise on.

For discussion sake let us assume there are only two fields assessee and
itat_order which are text fields; the latter has the entire judgment of
the court in text form.

Now I search using dismax against these 2 fields using a query like below

http://localhost:8983/solr/itat/select?q=additional+depreciationstart=20rows=30fl=assessee%2C+itat_order%2C+scorewt=xmlindent=truedefType=dismaxqf=assesseehttp://techgaruda.com:8983/solr/itat/select?q=additional+depreciationstart=20rows=30fl=assessee%2C+itat_order%2C+scorewt=xmlindent=truedefType=dismaxqf=assessee
^0.3+itat_order^0.2


For such a dismax query, the words additional depreciation (2 words without
quotes), we get results with additional and depreciation separately
occurring having higher score than results which have the words additional
depreciation occurring immediately together.  Why does this happen?

Shouldn't we ideally be getting exact matches of additional depreciation
first and then matches which have both the words but apart from each other
after these exact matches?  (In general when I search for A B shouldn't I
get matches with A B as they appear first and then A and B separated by
distance or singly occuring?)

Below I have pasted the score and # of occurences given for three results;
if you want I can share the text fields in these cases too.

(Also, for what its worth, the solr index uses only a
whitespacerfilterfactory and lowercasefilterfactory for querying and
indexing)

thanks
Vulcanoid

Re: simple tokenizer question

[Vulcanoid Developer]

Thanks for your email.

Great, I will look at the WordDelimiterFactory. Just to make clear, I DON'T
want any other tokenizing on digits, specialchars, punctuations etc done
other than word delimiting on whitespace.

All I want for my first version is NO removal of punctuations/special
characters at indexing time and during search time i.e., input as-is and
search as-is (like a simple sql db?) . I was assuming this would be a
trivial case with SOLR and not sure what I am missing here.

thanks
Vulcanoid

 Have you tried a WhitespaceTokenizerFactory followed by the

Re: Suggester - how to return exact match?

[Developer]

May be there is a way to do this but it doesn't make sense to return the same
search query as a suggestion (Search query is not a suggestion as it might
or might not be present in the index).

AFAIK you can use various look up algorithm to get the suggestion list and
they lookup the terms based on the query value (some alogrithm implements
fuzzy logic too). so searching Foo will return FooBar, Foo2 but not foo.

You should fetch the suggestion only if the numfound is greater than 0 else
you don't have any suggestion.

Re: Exact Match Results

[Developer]

You need to provide us with the fieldtype information..

If you just want to match the phrase entered by user, you can use
KeywordTokenizerFactory..

Reference:
http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters

Creates org.apache.lucene.analysis.core.KeywordTokenizer.

Treats the entire field as a single token, regardless of its content.

Example: http://example.com/I-am+example?Text=-Hello; ==
http://example.com/I-am+example?Text=-Hello;

Re: Exact Match Results

[Developer]

For exact phrase match you can wrap the query inside quotes but this will
perform the exact match and it wont match other results.

The below query will match only : Okkadu telugu movie stills

http://localhost:8983/solr/core1/select?q=%22okkadu%20telugu%20movie%20stills%22

Since you are using Edge N Gram filter, it produces so many tokens (as
below). You might not get the desired output. You can try using shingle
factory with standard analyzer instead of using edge n gram filter.

Re: Fuzzy Logic Implementation

[Developer]

Use the spell check component with collation..

Example:

http://localhost:8983/solr/spell?q=delll
ultrasharspellcheck=truespellcheck.extendedResults=truespellcheck.collate=true

My posts are NOT getting accepted by the mailing list.

[Developer]

For some reason, my posts are not getting accepted my mailing list even
though I am a subscriber for more than 3 years now. Did anything change in
recent past? Do I need to subscribe to this list again?

[Developer]

Thanks Shawn. Actually some of my posts are still pending while others were
successfully accepted by mailing list. I never used HTML formatting.. but
hopefully I am not listed as a spammer

Re: Replace NULL with 0 while Indexing

[Developer]

You can also use

SELECT ISNULL(myColumn, 0 ) FROM myTable
