Thanks Erick. TermsQueryParser worked for me.
Thanks & Regards,

Subject: Re: Passing IDs in query takes more time
Well, you're parsing 80K IDs and forming them into a query. Consider
what has to happen. Even in the very best case of the <other criteria>
being evaluated first, for every doc that satisfies that clause the inverted
index must be examined 80,000 times to see if that doc matches
one of the IDs in your huge clause for scoring purposes.
You might be better off by moving the 80K list to an fq clause like
fq={!cache=false}docid:(111 222 333).
Additionally, you probably want to use the TermsQueryParser, something like:
fq={!terms f=id cache=false}111,222,333
see:
https://cwiki.apache.org/confluence/display/solr/Other+Parsers#OtherParsers-TermsQueryParser
In any case, though, an 80K clause will slow things down considerably.
Best,
Erick
