Documenting a negated set against the universe of all posisble syntax
isn't feasible -- ie: the docs list what things QueryParser can do, not
the full list of all permutations of things it can't do.
Thats true, obviously but the point I was making was that the
queryparsersyntax page which is where I expect most novices (such as
myself) start with lucene seems to indicate that wildcards can be used
in, and this page is
as far as one should need to go to understand basic query syntax, this
page should be corrected.
Quoting:
'Terms: A query is broken up into terms and operators. There are two
types of terms: Single Terms and Phrases.
A Single Term is a single word such as "test" or "hello".
A Phrase is a group of words surrounded by double quotes such as "hello
dolly".
....
Wildcard Searches
Lucene supports single and multiple character wildcard searches.
To perform a multiple character wildcard search use the "*" symbol.
Multiple character wildcard searches looks for 0 or more characters. For
example, to search for test, tests or tester, you can use the search:
test*
You can also use the wildcard searches in the middle of a term.
'
there is nothing to indicate in the section on Wildcard Searches that it
can be performed only on Single word terms not Phrase terms.
It can't deal with Span Queries,
No they are never mentioned(,I don't even know what they are.), so it is
not a problem.
it can't handle fuzzy phrase queries,
no and it states this correctly ' Lucene supports fuzzy searches based
on the Levenshtein Distance, or Edit Distance algorithm. To do a fuzzy
search use the tilde, "~", symbol at the end of a Single word Term'
If you read the section on Proximity Searches (aka: PhraseQuery) you'll
eee it clearly says "Lucene supports finding words are a within a specific
distance away." ... note that word "word". It does *not* say "...finding
QUERIES are within...."
but why would I look here, I was just trying to understand query syntax,
