The queries I'm doing really aren't anything clever...just searching for
phrases on pages of text, sometimes narrowing results by other words that
must appear on the page, or words that cannot appear on the same page. I
don't have experience with those span queries so i can't say much about
them.
SpanTermQuery is a TermQuery and not a WildcardQuery. You could use a
SpanRegexQuery. You could also make your own SpanWildcardQuery based
on either WildcardQuery or SpanRegexQuery.
You should probably tell us a bit about the problem you try to solve
rather than asking about the solution y

Thanks for the tip,
but I can't imagine the number of documents google has to join in order

There must be a trick.
Maybe stopwords are not indexed alone but twice with previous and next

That's a phrase search, so it's conceivable google could be doing
something similar to nutch, whereby adjacent ngrams are indexed as
unique terms.
But if you do the same search without quotes:

Your query includeds apostrophes which tells google to include common
words in the query.
But, if you remove the apostrophes, you will still get results, as google
states:
"Google ignores stop words when they're placed in searches alongside less
common words. For example, a search for [ The
Hi Greg,
Thanks for quick and detailed answer.
What kind of queries do you run? Is it going to work for
SpanNearQueries/SpanNotQueries as well?
Do you also get the word itself at each position?
It would be great if I could search on the content of each payload as well,
but since the payload cont
Hi,
Look at this google query :
http://www.google.fr/search?q=%22HOW+at+at+of+a+A+a%22
What do you think about that concerning stop words?
Google has no stop words?

I now see my query-logic was flawed. In order to avoid matching all
