in reply to Re^2: search a large text file
in thread search a large text file
PostgreSQL does indeed have btree indexes, but also inverted indexes (GIN), and the excellent GIST index type. (it seems to me the btree type does well enough in this case; if you see my example below, where searching in a 223-million+ rows table takes a tenth of a millisecond).
PostgreSQL index-type docs here.
I'm just reacting to the juxtaposition of sqlite and postgres; really: SQLite, handy as it often is, can not be compared with a powerful database system like postgresql.
(And I should really try & compare Your Mother's example with KinoSearch, and see if he is right; maybe in the weekend... )
