Richard, 

Just a suggestion.

Would it make sense to ask one of your document maintainers to add
something similar to your explanation and add it to the "SELECT"
documentation page as a note to using the WHERE clause and the "INDEX"
documentation page


========================================================================

Note the "+" operator in front of the "type" field in the WHERE clause.
This + size makes that term of the WHERE clause an expression, rather
than a constraint on a column, and this disqualifies it from use by an
index.  That forces SQLite to use another query strategy.
========================================================================
