I am trying to optimize my search engine. Right now, I am running a strcmp between the search words the user entered and keywords stored in the database. I am trying to come up with a way so that the more matches the users search words has with the keywords the sooner it will show up in the search results.
For example, if the user search for “red apple painting” and I have two entries for that item with the following keywords 1. “old apple painting green” 2. “apple painting red new york” I would like the second entry to come up first in the search result because all of the users search words were found in the keywords stored in the db.
Any help on how I can achieve this?
Take a look at full text search.
You may also want to consider an external text search engine such as Lucene or Sphinx.
