Re: Cannot get "uf" (user fields) to work

[Emir Arnautovic]

Steve,
Your config should be like:

<requestHandler name="/select_group_a" class="solr.SearchHandler">
       <lst name="defaults">
         <str name="echoParams">explicit</str>
         <int name="rows">20</int>
         <str name="defType">edismax</str>
         <str name="qf">F3</str>
         <str name="fl">type,id,score</str>
         <str name="wt">xml</str>
         <str name="indent">true</str>
       </lst>
    </requestHandler>

This means when you query with "something" it will be equivalent to F3:something if you 
use standard parser. If you specify uf, than it will allow query to contain that field i.e. even 
you said in qf=F1 F2 F3, if you have in uf=F1, you will be able to define q=F1:something and it 
will search only F1. Otherwise it will not - did not use it so not sure if it will throw parsing 
error or will threat "F1:something" as query and search it in F1, F2 and F3.

Thanks,
Emir

Hi Emir,

Like I replied to Jack, I don't get it.  I need to see some concrete
examples.

Thanks

Hi Steve,
No - you should use qf to limit search to fields you want. If you do not
plan to allow users to explicitly state fields they want to search, you
don't have to use uf parameter. So, drop uf, and set qf to F3.

Thanks,
Emir

Hi Emir,

Are you saying I should remove "qf" if I want to use "uf"?  I just tried
that and got exception:

  Hi Steve,

You use qf to limit search on some fields.

Thanks,

  Hi Everyone,

I'm trying to utilize "uf" but it doesn't work.  My reading of it per:


https://cwiki.apache.org/confluence/display/solr/The+Extended+DisMax+Query+Parser
is I can use it to limit into which fields a search is performed.  E.g.:
If
my index has F1, F2, F3, F4, and I set "uf" to F3, than I should get
hits
on F3 only.

Here is my request handler:

     <requestHandler name="/select_group_a" class="solr.SearchHandler">
        <lst name="defaults">
          <str name="echoParams">explicit</str>
          <int name="rows">20</int>
          <str name="defType">edismax</str>
          <str name="qf">F1 F2 F3 F4</str>
          <str name="uf">F3</str>
          <str name="fl">type,id,score</str>
          <str name="wt">xml</str>
          <str name="indent">true</str>
        </lst>
     </requestHandler>

I also tried passing "uf" on the URL and it too didn't work.  I'm
getting
hits on terms that are in other fields.

Is my usage of "uf" wrong?

Thanks

Steve
