Right.

Wrong. It is in the database but not in "quickly searchable database".

This is a special search.

Indexing is good for texts but not for prices. Texts consist from words
and word forms. The one who searches for phrase usually need almost
exact match (i.e. if if he look for "typo" than "typo3" and "typo" are
both matches good but "mambo" is a bad match :))

For prices, range is usually more interesting than exact match, which
makes it very different from text (Noone will search for shares with
price set to $34.07, they will search for shares with price form $30 to
$40). Also, as you said, price changes quite often, so there is no
reason to *index* price data at all. If extension works with prices, it
should have its own search capabilities and search data directly.
