in thread Running SuperSearch off a fast full-text index.

The reason I think that SQLite would be useful is that if we want to separate the spider from indexer, finding the articles to update in the index is as simple as

SELECT * FROM ARTICLES WHERE LAST_UPDATED > $LAST_TIME_I_RAN
instead of searching the filesystem. Stored on the filesystem, we will need code to
  • search,
  • store, and
  • update
the documents. SQLite provides all of that for free. Want to move to a different machine? -- The database is a single file. Plus, who knows what other useful things SQLite's flexibility will allow us to do?

    I've worked on spiders that have used the file system, and spiders that have used databases. It's certainly cheaper to use the file system. But thinking about the size of the dataset, we can easily afford to put these records into a database. There are only c. 600,000 records, and they're small -- not even full web pages. I like the idea of using SQLite.
