This goes through a lot of loops. Might take a lot of time if "bigdb.tab" is really big enough.

Code:
#! /bin/bash

while read x
do
    while read f1
    do
        echo $x | grep -q -w $f1
        if [ $? -eq 0 ]
        then
            y=`echo "$x" | sed "s/\(.*\)\t.*$f1.*/\1\t$f1/"`
            while read f2
            do
                echo "$x" | grep -q -w $f2
                if [ $? -eq 0 ]
                then
                    echo -e "$y\t$f2" >> output.tab
                    break
                fi
            done < file2.tab
            break
        fi
    done < file1.tab
done < bigdb.tab

NAME
tracker-search - Search all content for keywords SYNOPSIS
tracker-search [OPTION...] EXPRESSION [EXPRESSION...] DESCRIPTION
tracker-search searches all indexed content for EXPRESSION. The resource in which EXPRESSION matches must exist (see --all for more infor- mation). All results are returned in ascending order. In all cases, if no EXPRESSION is given for an argument (like --folders for example) then ALL items in that category are returned instead. EXPRESSION One or more terms to search. The default operation is a logical AND. For logical OR operations, see -r. OPTIONS
-?, --help Give a short help message. -l, --limit=N Limit search to N results. The default is 512. -o, --offset=N Offset the search results by N. For example, start at item number 10 in the results. The default is 0. -r, --or-operator Use OR for search terms instead of AND (the default) -d, --detailed Show the unique URN associated with each search result. This does not apply to --music-albums and --music-artists. -a, --all Show results which might not be available. This might bebecause a removable media is not mounted for example. Without this option, resources are only shown if they exist. This option applies to all command line switches except --music-albums and --music-artists. -f, --files=EXPRESSION Search for files of any type matching EXPRESSION (optional). -e, --folders=EXPRESSION Search for folders matching EXPRESSION (optional). -m, --music=EXPRESSION Search for music files matching EXPRESSION (optional). --music-albums=ALBUM Search for music albums matching ALBUM (optional). --music-artists=ARTIST Search for music artists matching ARTIST (optional). -l, --images=EXPRESSION Search for images matching EXPRESSION (optional). -v, --videos=EXPRESSION Search for videos matching EXPRESSION (optional). -t, --documents=EXPRESSION Search for documents matching EXPRESSION (optional). -e, --emails=EXPRESSION Search for emails matching EXPRESSION (optional).
