Passing variables as values in Query Filter

[Mukundaraman valakumaresan]

Hi

The following query executes
http://localhost:8983/solr/collection1/select?wt=json&indent=true&q=locality:A<http://localhost:8983/solr/collection1/select?wt=json&indent=true&q=city:Chennai>
dyar

But I wanted something like the one below which is not working.

http://localhost:8983/solr/collection1/select?wt=json&indent=true&q=locality:$str&str<http://localhost:8983/solr/collection1/select?wt=json&indent=true&q=city:$str&str=Chennai>
="Adyar"

http://localhost:8983/solr/collection1/select?wt=json&indent=true&q=locality:<http://localhost:8983/solr/collection1/select?wt=json&indent=true&q=city:$str&str=Chennai>
getAdjacentLocalities("Adyar")

getAdjacentLocalities() is a custom function implemented.

Any suggestions.

Thanks & Regards
Mukund
