Hi Adrien,
Using the Groovy script, we modified the existing data in the document from
the application server itself for our case, but we still work on one
particular case as I discussed before in which we need to retrieve
documents based on two indexed fields having same value. For instance,
consider the documents contain two fields "place" and "city" and the search
query is like retrieving documents if the fields ("place" and "city") have
same values. Is there any way for this case in lucene 4.10.4 ( as we are
using this version currently) ?
