Thank you Hoss from correcting my understanding, again i missed this
concept of edismax.
Do we have any solrj class or helper to handle the scenario to pass on the
query terms (by stripping stopwords ) to edismax using solrj api.
for ex: if user queries for *"term1 and term2"* build and query to pass on
this to edismax so that this user query will be parsed as
*"parsedquery": "(+(DisjunctionMaxQuery((textSpell:term1)
DisjunctionMaxQuery((textSpell:term2))))/no_coord" *
*Thanks,*
*Rajesh**.*
