looking for code snippets or links to examples of the following;
- Have a database with multiple fields that will be searched against (happens to be PostgreSQL in this instance, but we can migrate any MySQL based examples/code) - We wish to score search results - ie: a match in "keywords" is worth 5 points, "title" worth 3, and "description" worth 1, perhaps even so far as multiple matches producing multiples of the point value(though that can be a later consideration) - Once we get the results, we would want to display in the order of the scoring, most points first etc...
Obviously there are convoluted ways to accomplish, but I am looking to maximize the database performance, limit the number of recursive searches, and use the database/PHP each handle their portion of the search/score/ranking based on their strengths and use of system resources.
appreciate any feedback
Dave
There is a module for Postgres that does indexed full text searching, with ranking:
