Re: Using a RequestHandler to expand query parameter

[jimtronic]

So, the problem I found that's driving this is that I have several phrase
synonyms set up. For example, "ipod mini" into "ipad mini". This synonym is
only applied if you submit it as a phrase in quotes. 

So, the pf param doesn't help because it's not the right phrase in the first
place.

I can fix this by sending in the query as ("ipod mini" ipod mini).

As someone else already said, you can write a custom request handler and
reference it in a handler definition in your solrconfig.xml file.  The
sky's the limit for that -- if you can write the code, Solr will use it.

This *specific* example that you've given is something that the edismax
parser will give you out of the box, when you define the qf and pf
parameters.  It will automatically search the individual terms you give
on the fields in the qf parameter, *and* do a phrase search for all
those terms on the fields in the pf parameter.

Re: Using a RequestHandler to expand query parameter

[jmlucjav]

this is easily doable by a custom (java code) request handler. If you want
to avoid writing any java code, you should investigate using
https://issues.apache.org/jira/browse/SOLR-5005 (I am myself going to have
a look at this interesting feature)

Using a RequestHandler to expand query parameter

[jimtronic]

I would like to send only one query to my custom request handler and have the
request handler expand that query into a more complicated query.

Example:

*/myHandler?q=kids+books*

... would turn into a more complicated EDismax query of:

*"kids books" kids books*

Is this achievable via a Request Handler definition in solrconfig.xml?

Thanks!
Jim
