Re: Fwd: Is there a front-end for using xapian-omega rather than the terminal? Could a Xapian database be accessed from web-browsers?

A Xapian index is not a text file, rather it's a directory of binary
files, so naming it `.txt` would be confusing.

This isn't really the right place to seek help in setting up a
particular webserver, and it's also not really my area of expertise,
but the relevant apache documentation is here:

https://httpd.apache.org/docs/2.4/howto/cgi.html#configuring

You don't.

You configure apache to map a URL on the website it is serving to the
omega CGI, which might be

https://example.org/cgi-bin/omega

or

https://example.org/omega.cgi

(which correspond to the ScriptAlias and AddHandler approaches in
the Apache docs).

Then when a web browser loads that URL, the page it loads is generated
by omega CGI program on the server.

Use the omindex program that comes with xapian-omega.

It may be possible to create a database with Recoll and search it with
the omega CGI, but whether that works properly depends on exactly how
Recoll indexes its documents which I'm not familiar with.  There's a
lot of flexibility in how you can use a Xapian database, and
xapian-omega makes some assumptions (which are matched by omindex but
may not be by every program which can create a Xapian database).

There's not a good reason to mix and match in this case though as
omindex can index all the common formats (and many less common ones).
