Exact and Partial Matches
Dear Experts,
I have a requirement for the exact matches and applying alphabetical
sorting thereafter.
To illustrate, the results should be sorted in exact matches and all later
alphabetical.
So, if there are 5 documents as below
Doc1
title: trees
Doc 2
title: plum trees
Doc 3
title: Money Trees (Legendary Trees)
Doc 4
title: Cork Trees
Doc 5
title: Old Trees
Then, if user searches with query term as 'trees', the results should be in
following order:
Doc 1 trees - Highest Rank
Doc 4 Cork Trees - Alphabetical afterwards..
Doc 3 Money Trees (Legendary Trees)
Doc 5 Old Trees
Doc 2 plum trees
I can achieve the alphabetical sorting by adding the title sort
parameter, However,
Solr relevancy is higher for Doc 3 (due to matches in 2 terms and so
it arranges
Doc 3 above Doc 4, 5 and 2).
So, it looks like:
Doc 1 trees - Highest Rank
Doc 3 Money Trees (Legendary Trees)
Doc 4 Cork Trees - Alphabetical afterwards..
Doc 5 Old Trees
Doc 2 plum trees
Can you tell me an easy way to achieve this requirement please?
I'm using Solr 4.0 and the *title *field is defined as follows:
<fieldType name="text_wc" class="solr.TextField" positionIncrementGap="100"
>
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.WordDelimiterFilterFactory"
stemEnglishPossessive="0" generateWordParts="1" generateNumberParts="1"
catenateWords="1" catenateNumbers="1" catenateAll="1" splitOnCaseChange="1"
splitOnNumerics="0" preserveOriginal="1" />
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.WordDelimiterFilterFactory"
stemEnglishPossessive="0" generateWordParts="1" generateNumberParts="1"
catenateWords="1" catenateNumbers="1" catenateAll="1" splitOnCaseChange="1"
splitOnNumerics="0" preserveOriginal="1" />
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>
Many Thanks in advance,
Sandeep

An alternative would be a custom SearchComponent that post-processes hits.

Thanks Erick,
I tried grouping and it appears to work okay. However, I will need to
change the client to parse the output..
&fq=title:(tree)&group=true&group.query=title:(trees) NOT
title_ci:trees&group.query=title_ci:blair&group.sort=title_sort
desc&sort=score desc,title_sort asc
I used the actual query as the filter query so my scores will be 1 and then
used 2 group queries - one which will give me exact matches and other that
will give me partial minus exact matches.
I have tried this with operators too and it seems to be doing the job I
want, do you see any issue in this?
Thanks again for your reply and by the way thanks for SOLR-4662.

I don't think you can do that. You're essentially
trying to mix ordering of the result set. You
_might_ be able to kludge some of this with
grouping, but I doubt it.
You'll need two queries I'd guess.
