Dear Nutch Staff,
I am using nutch to develop a search engine for a specific niche.
The system is running fine but I realized that might have some possible mistake with the Boolean query. Or maybe I am doing something wrong building it.
Executing the queries bellow, I noticed that the Boolean operator “OR” brings the same result of total matching documents as the operator “AND”.
DOG - (out of 872404 total matching documents) CAT - (out of 818659 total matching documents) DOG OR CAT - (out of 151041 total matching documents) DOG AND CAT - (out of 151041 total matching documents)
I also checked the Yahoo Research Lab - Nutch Open Source Web Search Demo at http://research.yahoo.com/demo/nutch/search.xml?query=enterprise%2Bsearch, and I got the same behavior for the operator "OR".
Would you please let me know if this is my mistake building the query?
Thank you for your attention.
Best Regards, Andrey
