this did not work, any suggestions please?
QueryParser parser = new QueryParser(columns[0], analyzer) ;
Query query5 = parser.parse(q+"~");
i cant set the slop value like
parser.setPhraseSlop(slopValue);
i still see the query printed as with value 2:
Query5:: :~2
Best regards
On
Ok, found answer to this question:
parser.setPhraseSlop(slopValue);
Thanks

i see the query
Case 1. Stopwords are irrelevant. If you sreach field:(a AND b) you're
asking if both appear in the field, and that's the only question. It
doesn't matter what other words are in the field. It doesn't matter whether
they're close to each other.
Case 2. Yep.

There is PhraseQuery, too, but lets consider two cases:
case1: that PhraseQuery is not being used:
then should i add to standard filter’s stopwords also the french stopwords both
at index & search times? can i just add them at search time and keep old index
as it is? [gotta disable this editing

case2: that
That is not what i am looking for. Thanks.
c b search string finds
a b
but how cant find
a de la b
so i will try french stopwords.
Doing that i am using 8 queries like the ones i mentioned.

Phrase search is looking for words next to each other. A phrase search on the
text “my dog has fleas” would succeed for “my dog” or “has fleas” but not “my
fleas” since the words are not right next to each other. “my fleas”~3 would
succeed because the “~3” indicates that the words can have
i guess so
what is phrase search?
c b is searched do you expect a de la b?
Thanks

Not sure we’re talking about the same thing. I was talking specifically about
_phrase_ searches. If all you want is the clause you just said, phrases are not
involved at all and the presence or absence of intervening words is totally
unnecessary. This assumes your field type tokenizes the input
In this case search string is c b
and then search query has 8 combos
including two cases with c b ~ which means find all containing c And b and c Or
b ( two separate queries having ~ )
and then i can find a b but not a de la b without French stopwords.
Thanks

Lucene won’t ignore these unless you tell it to via stopwords.
This is a problem no matter how you look at it. If you do put in stopwords, the
word _positions_ are retained. In your example,
word position
a 1
de 2
la 3
b 4
If you remove “de” and “la” via
Thanks Erick there is a pattern i cant catch in my results such as:
a de la b
i catch “a b” though.
I though Lucene might ignore those automatically while creating index.

Use stopwords, although it's becoming less of a concern, why do you think
you need to?

Hi,-
What is the (most efficient) way to
ignore “de la” kinda connectors
in a string at index or search time?
Thanks
