Hi Mike,
Your solution work! I've been trying it with PhraseQuery and It works
pretty good.
Thank you so much.
David.

I believe you can accomplish what you are talking about using PhraseQuery,
say: note that it has
public void add(Term term, int position)
which does enable searching for multiple terms at the same position
and you should be able to encode different kinds of attributes using text
tricks like I suggested, or with payloads: I'm less clear about how to use
the payloads in queries though

What you propose is good if you want to index only the pos of a token. But
I want to index some extra info, such as "lemma" of a token, phonetic
encoding, etc. Sorry, I was not too general in my previous post.
Imagine you want to ask this:
an adj whose lemma is "quick" followed by "brown" followed by a noun whose
phonetic enconding is "fots".
So, the main problem is you cannot ask if several "synonyms" exist at the
same position.
Thank you Michael for your answer.

What if you indexed every word with two synonyms: the plain unadorned
word
and a token formed by concatenating the pos and the word with some
unusual
separator character?
For example, "the quick brown fox" would be:
{ the | article:the } {quick | adj:quick } { brown | adj:brown } { fox |
noun:fox }
with punctuation to suggest the token graph

After many google searchs I decided to post my problem here hoping that
someone help me. What I want to achieve is to perform queries as follows
(Don't worry about the query format):
q1: (adjective) "jumps" (preposition) // any adj followed by "jumps"
followed by any prep.
q2: (adjective:brown) "jumps" (preposition) // brown as adj. followed by
"jumps" followed by any prep.
q3: (adjective:brown) (verb:jumps) (preposition) // brown as adj
followed
by jumps as verb followed by any preposition.
In a more general form, what I want is
(POS[:specific_word]) (POS[:specific_word]) (POS[:specific_word])
For that, I have the text tagged as follows:
the|[pos:DT][lemma:the] quick|[pos:JJ][lemma:quick]
brown|[pos:JJ][lemma:brown] fox|[pos:NN][lemma:fox]
jumps|[pos:NNS][lemma:jump] over|[pos:IN][lemma:over]
the|[pos:DT][lemma:the] lazy|[pos:JJ][lemma:lazy]
dog|[pos:NN][lemma:dog]
The first thing I thought was to index extra info of each term as
payload
and using PayloadNearQuery after in order to access to the payload of
each
span. The problem is that PayloadNearQuery match the terms first and
then
access its payload, so none of the 3 above queries will work. (correct
me
if I'm wrong)
The second thing I thought was to index extra info as synonyms of the
term
but, this way, the second query won't work since I can't ask if the
first
term is an adj and the specific word "brown" simultaneously.
Any way to address this problem, suggestions, etc. will be appreciated.
David.
