Populate From A Query Using CFIndex
Now that we have a somewhere to store our search index we now need to populate it with data. To do this we use the cfindex tag. In this case I am populating the index using the title and description of my blog entries.
Note how I specify title and description for the body as I want to use the description and blog titles only as valid search data. However I could have easily added the blog content itself or any available datapoints.
<!--- First get some data to index --->
WHERE published = 1
<!--- Then index it --->
When we use the action="update" attribute of the cfindex tag the key value determines if data should be over ridden or appended. This means that we can run a second update on the same index to add in new data and the old data will not be changed unless there is an existing record with the same key value in which case the old data would be over written.
Populate Index From A Directory
We can also populate our index from static files or cfml templates. To do this we specify the path to the directory containing our static pages.
I have not tried mixing the two methods of indexing data but I believe that it is possible. (someone please correct me if I am wrong.)
Search The Index Using CFSearch
Now that we have indexed data lets run a search.
<!--- Search all published blog entries for "coldfusion rocks" and return a query resultset --->
<cfsearch name="searchResults" collection="publishedBlogs" criteria="coldfusion rocks">
So there you have it. The only thing left to do is build a search form to submit to the cfsearch tag and format results nicely.
