Does Solr support 'Value Search'?
Hi folks,
Just wondering if there is a query handler that simply takes a query string
and search on all/part of fields for field values?
e.g.
q=*admin*
Response may look like
author: [admin, system_admin, sub_admin]
last_modifier: [admin, system_admin, sub_admin]
doctitle: [AdminGuide, AdminManual]

Sure, Lucene is kind of column oriented DB. if the same text occurs in two
different fields there is no any relation between such terms i.e. BRAND:RED
vs COLOR:RED. The only thing I can suggest you is build separate index (in
solr core) with docs like token:RED; fields:{COLOR, BRAND,,} or giving your
initial sample:
{token:admin; field:author; original_text:system_admin}
{token:admin; field:author; original_text:admin}
{token:admin; field:doctitle; original_text:AdminGuide}
...
then you can search by token:admin and find such occurrence documents.

Thanks Kuli and Mikhail,
Using either termcomponent or suggester I could get some suggested terms but
it's still confusing me how to get the respective field names. In order to
get that, Use TermComponent I'll need to do a term query to every possible
field. Similar things as using SpellCheckComponent. CopyField won't help
since I want the original field name.
Any suggestions?

Ok. this explanation is much cleaner. Have you tried to invoke
http://wiki.apache.org/solr/TermsComponent/ against all fields which you
need?

Hi Bing,
hmh, I implemented myself an autosuggest component that does exactly
this. You could specify which field you wanted to query, give an
optional weight to them, and the component returned a list of all fields
and values beginning with the queried string. Either combined or per
field, depending on your configuration.
However, that was with Solr 1.4.0, when there was no genuine suggest
component available. Since then, the Suggester component has been
implemented: http://wiki.apache.org/solr/Suggester/
This relies on the spell check dictionary and works better than a simple
term dictionary approach. And that's the reason why I didn't bother my
old code any more.
So maybe you're simply looking for the suggester component? If not, I
can try to make my old-style component work with a current Solr version
and spread it around. Just tell me.
Greetings,
Kuli

Not quite understand but I'd explain the problem I had. The response would
contain only fields and a list of field values that match the query.
Essentially it's querying for field values rather than documents. The
underlying use case would be, when typing in a quick search box, the drill
down menu may contain matches on authors, on doctitles, and potentially on
other fields.
Still thanks for your response and hopefully I'm making it clearer.

Ok. It seems to me you can configure
http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters#solr.WordDelimiterFilterFactoryfor
index-time to produce "admin" term from all your docs above, after
that
you'll be able to match by simple term query.
Is it what are you looking for?

Thanks for the response but wait... Is it related to my question searching
for field values? I was not asking how to use wildcards though.
