Xapian discuss - Feb 2007 - Using scriptindex with omega and date searches.

I was attempting to incorporate the START and END cgi parameters to 
omega to limit my query but it wasn't working.  I noticed that the 
generated query consisted of a bunch of filter terms such as:

M200110 OR M200111 OR D20011201 OR D20011202

however when I went into godmode I saw the D terms but no M terms.  I 
reasoned that omnindex must generate something to put in the DB like

month: field=month index=M

I didn't find that documented anywhere, but when I added that to my 
index file and added a term such as

month=200110

to each document, the search with START and END seemed to work.

Am I correct that I had to do it myself?  Or was there some way I could 
have modified the index to automatically generate the M terms?

If the former, I'm going to write it up and put it on the wiki 'cause 
it's really not as well documented as I would have liked.  Perhaps a 
note in the cgi discussion near the START, END and SPAN that says these 
are only valid if you use omindex would be helpful.

Jim.

Just use the scriptindex "date" action - it can produce the required
terms from either a Unix time_t value or a string of the format
YYYYMMDD.  It's documented in docs/scriptindex.txt.
