TermsComponent from deleted document
Hi,
http://wiki.apache.org/solr/TermsComponent states that TermsComponent will
return frequencies from deleted documents too.
Is there anyway to omit the deleted documents to get the frequencies.
I know there is a facets which can be used. Is it recommended to use facets
for autosuggest feature?
Thanks,
Manish.

I'd use the suggester:
http://wiki.apache.org/solr/Suggester
The suggester can give a collation. The TermsComponent can't do that.
The suggester builds on top of the spellchecking infrastructure, so
should be easy to use if you're familiar with that.

Which is preferable? using TermsComponent or Facets for autosuggest?

not really -- until a deleted document is expunged from segment merging,
they are still included in the term stats which is what the TermsComponent
looks at.
If having 100% accurate term counts is really important to you, then you
can optimize after doing any updates on your index - but there is
obviously a performance tradeoff there.
