Steve Rowe commented on LUCENE-4981:
------------------------------------
The comment in TestRandomChains says:
{code:java}
// TODO: corrumpts graphs (offset consistency check):
PositionFilter.class,
{code}
which is what made me wonder what about the nature of brokenness: why are
offsets a problem?
I agree, Robert, PositionFilter corrupts by design. And if we do end up
keeping it, position length should be addressed (it's not now), maybe by always
setting it to 1.
> Deprecate PositionFilter

> According to the documentation
> (http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters#solr.PositionFilterFactory),
> PositionFilter is mainly useful to make query parsers generate boolean
> queries instead of phrase queries although this problem can be solved at
> query parsing level instead of analysis level (eg. using
> QueryParser.setAutoGeneratePhraseQueries).
> So given that PositionFilter corrupts token graphs (see TestRandomChains), I
> propose to deprecate it.
