Hi,
Span query family would be a pure query-time solution, SpanNotQuery in
particular.
SpanNearQuery include = new SpanTermQuery(new Term(FIELD, "world");
SpanNearQuery exclude = new SpanNearQuery(new SpanQuery[] {
new SpanTermQuery(new Term(FIELD, "hello")),
new SpanTermQuery(new Term(FIELD, "world"))},
0,
true);
SpanQuery finalQuery = new SpanNotQuery(include, exclude)
This finalQuery supposed to retrieve documents that have the term "world" but
not as a part of "hello world".
Is your list of phrases query dependent? If yes how many phrases per-query?
Or you have a global list of phrases?

Hi,
The list of phrases wil be relatively dynamic, so changing the indexing
process isn't a very good solution for us.
We also considered using a PostFilter or adding a SearchComponent to filter
out the "bad" results, but obviously a true query-time support would be a
lot better.
