Quick search using xapian "omega"

A little hack to search current directory using Xapian's omega.

#!/bin/bash

# Minimal search using Xpians Omega (http://xapian.org/docs/omega/overview.html)
# Use "omsearch -i" to index current directoy, then use "omsearch QUERY" to
# search


index() {
    mkdir .omega
    cat >> .omega/omega.conf << EOF
    database_dir $PWD/.omega
    template_dir /var/lib/xapian-omega/templates
    log_dir /tmp
EOF
    omindex --db .omega/default .
}

search() {
    omega=/usr/lib/cgi-bin/omega/omega
    config=$PWD/.omega/omega.conf
    results=.omega/results.html
    OMEGA_CONFIG_FILE=$config $omega "P=$1" "HITSPERPAGE=1000" > $results
    egrep -o '<B><A HREF=".*"' $results | cut -d\" -f2 | \
        xargs -i printf ".%s\n" {}

}

USAGE="usage: $(basename $0) [-i | QUERY]"

    case $opt in
