PhraseQuery can indeed be used to represent a multi-token synonym.
In fact, I mis-spoke before: MultiPhraseQuery can also represent a
multi-token synonym when the multiple tokens are all the same except in one
spot.

i should have asked this way as Mike made clear for MultiPhraseQuery:
is PhraseQuery ok to account for synonyms?

Ok, Mike, that was very helpful.
Now, i think i should use BooleanQuery with PhraseQueries but will
PhraseQuery be able to handle all synonyms- multi or single term?
What is the best way for this:
i have multiple tokens and i want to be able to do a cheap fuzzy search.

Yes, +1 for a patch to improve the docs!
MultiPhraseQuery only works for single term synonyms, and is usually
produced by query parsers when the incoming query text had single term
synonyms matching, I think? The query parser will use other (span?)
queries for multi token synonyms.
I think the e
FuzzyQuery seems also not suitable for me.
PrefixQuery can be one token only, right?

i want to have a BooleanQuery or MultiPhraseQuery (i cant decide between
these two) with an index which considers synonyms already.
One disadvantage of MultiPhraseQuery is that it need
bq. i wish the Javadocs has examples like PhraseQuery Javadocs gave.
This is where someone coming into the examples for the first time is
invaluable, javadoc patches are most welcome! It can be hard to back
off enough to remember what the confusing bits are when you wrote the
code ;)

Any suggestions please?
Two main questions:
- how do synonyms get utilized by MultiPhraseQuery?
- how do we get second token "app" applied to the example on
MultiPhraseQuery javadocs page? (and how do we get Terms[] array from
Terms object?)
Now three questions :)
i wish the Javadocs has exam
Trying to implement the example on
https://lucene.apache.org/core/6_6_1/core/org/apache/lucene/search/MultiPhraseQuery.html
// A generalized version of PhraseQuery, with the possibility of adding
more than one term at the same position that are treated as a
disjunction (OR). To use this class
OK, phew :) Thanks for bringing closure...

Hi,
seems there is a custom impl of MultiPhraseQuery used in the system,
which uses (and maybe misuses) Lucene's MultiPhraseQuery that could be
the reason of slowdown. I've tried running sample Lucene's
MultiPhraseQuery in an infinite while loop printing out times for
every 1000 executions and coul

By "slowing down over time" do you mean you use the same index (no new
docs added) yet running the same MPQ over and over you see it taking
longer to execute over time?

Can you checkout latest 3.1 branch @
https://svn.apache.org/repos/asf/lucene/dev/branches/lucene_solr_3_1
And test if it solves your issue. There was aproblem in PhraseQuery's
internal sorting and quicksort. It does not slowdown over time, but with
type of query (how many terms the phrase contains
Nice catch -- thanks! I will fix.
