Subject RE: OR query
Date Thu, 10 Jan 2013 18:36:27 GMT
If the fields you're querying are of type String (1 token), then you need to escape the whitespace
with a backslash, like this:

label:ian\ paisley


If they are of type Text (multiple tokens), sometimes you need to explicitly insert "AND"
between each token, either with:

label:(ian AND paisley)

or

label:(+ian +paisley)

I think this is the case with edismax, which somewhat supports boolean queries but with caveats...

You can also turn debugQuery on to figure out why things are not matching.

Subject: Re: OR query

I've tried both ways and I still get zero results with this.
Even though name_long:"paisley, ian" will return results.

<str name="fq">name_long:"paisley, ian"</str>
<str name="q">
(constituencies:(ian paisley) OR label:(ian paisley) OR office:(ian
paisley))
</str>
