Uwe Schindler commented on LUCENE-3338:
---------------------------------------
bq. I wondered that too, so I checked. Both AutomatonQuery and TermRangeQuery
special-case these to generate a simple TermsEnum, so the same. It makes sense
to optimize: this query could easily be generated by some app.
And for NumericRangeQuery this is even faster, as it will generate a query that
only enumerates the lowest precision terms (all of them). For e.g.
precisionStep 4 this would be 16 terms only :-) So no such optimization is
needed for NRQ.
bq. Uwe, raise your hand if you want me to hold the commit and sorry for taking
over your JIRA
It's all fine to combine both commits! I had not looked in 3343 because I
thought it's for the good old default QP... We should add changes at the end!
