Suggester spellcheck component and infix

[Kai Schlamp-2]

Does the suggester component of Solr also support infix search? (like
.*ompute.*)

No, it seems that I missed that completely. Thank you, Afroz. It works fine
now.

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.

Unfortunately I have to use Solr 1.4.x or 3.x as one of the interfaces to
access Solr uses Sunspot (a Ruby Solr library), which doesn't seem to be
compatible with 4.x.

 Kai, try SOLR-1086 with Solr trunk instead if trunk is OK for you.

 Subject: Problem with field collapsing of patched Solr 1.4
 
 Hello.
 
 I just tried to patch Solr 1.4 with the field collapsing patch  of
 https://issues.apache.org/jira/browse/SOLR-236. The patching and  build
 process seemed to be ok (below are the steps I did), but the  field
 collapsing feature doesn't seem to work.
 When I go to `http://localhost:8982/solr/select/?q=*:*` I correctly
 get 10 documents  as result.
 When going to 
`http://localhost:8982/solr/select/?q=*:*collapse=truecollapse.field=tag_name_sscollapse.max=1`

 (tag_name_ss  is surely a field with content) I get the same 10 docs as
 result back. No  further information regarding the field collapsing.
 What do I miss? Do I have  to activate it somehow?
