---------------------------------------
PhraseQuery.Builder:
public Builder add(Term term) {
return add(term, positions.isEmpty() ? 0 : 1 + positions.get(positions.size()
- 1));
}
/**
* Adds a term to the end of the query phrase.
* The relative position of the term within the phrase is specified explicitly,
but must be greater than
* or equal to that of the previously added term.
* A greater position allows phrases with gaps (e.g. in connection with
stopwords).
* If the position is equal, you most likely should be using
* \{@link MultiPhraseQuery} instead which only requires one term at each
position to match; this class requires
* all of them.
*/
public Builder add(Term term, int position) {
...
I used the prev api add(term), but there is another api which can specify an
extra position argument.
Here in this case, maybe i should pass in positions 0 2 4 6 7, which can be got
from analyzing of raw query text...
