Getting query fields in a custom SearchHandler

[Marc SCHNEIDER <ma...@gmail.com>]

Hi all,

I wrote my own SearchHandler and therefore overrided the handleRequestBody
method.
This method takes two input parameters : SolrQueryRequest and
SolrQueryResponse objects.
The thing I'd like to do is to get the query fields that are used in my
request.
Of course I can use req.getParams().get("q") but it returns the complete
query (which can be very complicated). I'd like to have a simple map with
field:value.
Is there a way to get it? Or do I have to write my own parser for the "q"
parameter?

Thanks in advance,
Marc.

Hi,

I reply to myself :-)
The solution is to use this utility class :
org.apache.solr.search.QueryParsing. Then you can do:

Query luceneQuery = QueryParsing.parseQuery(req.getParams().get("q"),
req.getSchema());

Then with luceneQuery you can use the extractTerms method.
