But does `Subject:#KEYWORD' work? >=20 > `#' seems to be an abbrev for `.*'. You've neatly summed up the reason I say it is difficult. Trying: C-u G G Query: 'Subject:#queries' or Query: Subject:#queries Either way produces: Invalid read syntax: "#" Query: Subject:.*queries Invalid read syntax: "." Even: Query: ^Subject: example queries for nnir or=20 Query: Subject: example queries for nnir with and without single quotes Wrong type argument: listp, example Trying to use the ";" operator (even though it would leave a gaping whole for false hits):=20 Query: Subject:;queries=20 End of file during parsing All the above leave room for false hits without the "^".=20=20 I think this points up the weakness I mentioned. And a good reason why it would be nice if RE were usable in the queries of glimpse. It appears that freeWAIS get around this problem neatly by use of `fields' as you've described.=20
