Fumiaki Yamaoka updated SOLR-629:
---------------------------------
Attachment: SOLR-629.patch
I'm working with Walter at Chegg. I have attempted to port the work Walter has
done to make fuzzy match work on qf field on Solr 3.3 to Solr 4.7 branch.
Please see the attachment for the changes. Would appreciate some feedback.
> Fuzzy search with DisMax request handler
> ----------------------------------------
>
> Key: SOLR-629
> URL: https://issues.apache.org/jira/browse/SOLR-629
> Project: Solr
> Issue Type: Improvement
> Components: query parsers
> Affects Versions: 1.3
> Reporter: Guillaume Smet
> Priority: Minor
> Attachments: SOLR-629.patch, dismax_fuzzy_query_field.v0.1.diff,
> dismax_fuzzy_query_field.v0.1.diff
>
>
> The DisMax search handler doesn't support fuzzy queries which would be quite
> useful for our usage of Solr and from what I've seen on the list, it's
> something several people would like to have.
> Following this discussion
> http://markmail.org/message/tx6kqr7ga6ponefa#query:solr%20dismax%20fuzzy+page:1+mid:c4pciq6rlr4dwtgm+state:results
> , I added the ability to add fuzzy query field in the qf parameter. I kept
> the patch as conservative as possible.
> The syntax supported is: fieldOne^2.3 fieldTwo~0.3 fieldThree~0.2^-0.4
> fieldFour as discussed in the above thread.
> The recursive query aliasing should work even with fuzzy query fields using a
> very simple rule: the aliased fields inherit the minSimilarity of their
> parent, combined with their own one if they have one.
> Only the qf parameter support this syntax atm. I suppose we should make it
> usable in pf too. Any opinion?
> Comments are very welcome, I'll spend the time needed to put this patch in
> good shape.
> Thanks.
