Anne van Kesteren gave me some code to make intelligent searches inside WordPress and I wrapped it up in a nice install tutorial. Some of the features of this hack includes
-text based “fuzzy” searches within WordPress
-a nice Google like interface which is very customizeable
-search results with decreasing relevance to search topic
-trap for words which are less than four letters long, the search then gets routed through the default WP search
-”Next results” button which shows the next 10 (or less) results in relevance
-very simple installation with no effect on future upgrades
Test install is on this blog. Simply search for something from the form on the right.
Please post suggestions/bugs.
