This just implements ReversedWildcardFilter, which while also in Solr should be readily adaptable to lucene-only.
In general you want to do some trick like this. Otherwise it doesn't scale well as conceptually Lucene has to enumerate _all_ the terms to assemble the actual list of contained terms. I.e. say you are searching for *what There's no way to know what terms match unless you look at them all, which doesn't scale when the number of terms gets huge. You might be able to do something with ngrams too. Best, Erick On Mon, Jul 23, 2018 at 12:07 PM, Evert Wagenaar <[email protected]> wrote: > Thanks Eric, > > I see only Solr documents in there.
