Can I Do Reverse Search?
Hi,
Normally, lucene or Nutch can match query "nike shoe
-blue" with "red nike shoe".
But what about matching "red nike shoe" with query
"nike shoe -blue"? It is the other way around. Can I
do it with a combinations of API?
Many thanks.

yes, but I will have to do it for each ad as I stated

Re: Can I Do Reverse Search?
Posted by Sam Lee <vi...@yahoo.com>.
Yes, I thought of that. But since the ads have
negative keywords, it's very possible for the webpage
to match the ads but not the other way around because
of the negative keywords. So the system cannot be
sure that the ads match the webpage until it uses ads'
keyword and negative keywords to rematch the webpage.
This is a lot of resource for having each ad to match
the webpage again..
webpage www.mysite.com --match--> ad1.....ad101
Then I match each ad with the webpage.
But due to negative keywords:
ad1....ad100 --NOT match--> www.mysite.com
ad101 --match--> www.mysite.com
# of queries = 102
If there is a way to match content with boolean
keywords, then # of query is 1 only. Huge difference!
Any idea how to accomplish this?

Index the keywords of your ads with lucene.
Extract all words from your page (ajax), remove stop words, build a
query from the page words by connect the words with OR and you will
find the best matching ad.
You may need to limit the words per page or set the maximum clauses
to a much higher number.

Re: Can I Do Reverse Search?
Posted by Sam Lee <vi...@yahoo.com>.
ok, I am implementing a google adsense/adwords-like
system. For examples, the website has keywords "nike
red shoe", so it can match text ad with keywords "nike
shoe -blue". Of course, I can always use the text ad
keywords to match the website's keywords. But it will
take too much resource to have all ads to rematch the
new websites whenever new websites joins the ad
network. So I need a way for the new websites to
"reverse match" the text ads.
So if new website has "nike red shoes" as keywords,
then it should match all text ads with "nike shoes
-blue". The only difference is that it is doing it in
reverse.
many thanks.

How fast is MemoryIndex? For examples, I have a
webpage indexed, and I have 100000 queries with
negative keywords to match against this webpage. How
much faster is it comparing to using normal method to
match the same 100000 queries to this webpage?

Sam - I'm not quite sure I follow you, but let's see if this fits...
you want to have a document and see if a query matches it? Please
elaborate more on what you're after. Maybe what you're looking for
is the contrib/memory and the MemoryIndex within that Subversion area.
