Searching on the command line

There are several ways to obtain search results as a text stream, without a graphical interface:

  • By passing option -t to the recoll program, or by calling it as recollq (through a link).

  • By using the recollq program.

  • By writing a custom Python program, using the Recoll Python API.

The first two methods work in the same way and accept/need the same arguments (except for the additional -t to recoll). The query to be executed is specified as command line arguments.

recollq is not built by default. You can use the Makefile in the query directory to build it. This is a very simple program, and if you can program a little c++, you may find it useful to taylor its output format to your needs. Not that recollq is only really useful on systems where the Qt libraries (or even the X11 ones) are not available. Otherwise, just use recoll -t, which takes the exact same parameters and options which are described for recollq

recollq has a man page (not installed by default, look in the doc/man directory). The Usage string is as follows:

        recollq: usage:
        -P: Show the date span for all the documents present in the index
        [-o|-a|-f] [-q] <query string>
        Runs a recoll query and displays result lines. 
        Default: will interpret the argument(s) as a xesam query string
        query may be like: 
        implicit AND, Exclusion, field spec:    t1 -t2 title:t3
        OR has priority: t1 OR t2 t3 OR t4 means (t1 OR t2) AND (t3 OR t4)
        Phrase: "t1 t2" (needs additional quoting on cmd line)
        -o Emulate the GUI simple search in ANY TERM mode
        -a Emulate the GUI simple search in ALL TERMS mode
        -f Emulate the GUI simple search in filename mode
        -q is just ignored (compatibility with the recoll GUI command line)
        Common options:
        -c <configdir> : specify config directory, overriding $RECOLL_CONFDIR
        -d also dump file contents
        -n [first-]<cnt> define the result slice. The default value for [first]
        is 0. Without the option, the default max count is 2000.
        Use n=0 for no limit
        -b : basic. Just output urls, no mime types or titles
        -Q : no result lines, just the processed query and result count
        -m : dump the whole document meta[] array for each result
        -A : output the document abstracts
        -S fld : sort by field <fld>
        -s stemlang : set stemming language to use (must exist in index...)
        Use -s "" to turn off stem expansion
        -D : sort descending
        -i <dbdir> : additional index, several can be given
        -e use url encoding (%xx) for urls
        -F <field name list> : output exactly these fields for each result.
        The field values are encoded in base64, output in one line and 
        separated by one space character. This is the recommended format 
        for use by other programs. Use a normal query with option -m to 
        see the field names.
      

Sample execution:

recollq 'ilur -nautique mime:text/html'
      Recoll query: ((((ilur:(wqf=11) OR ilurs) AND_NOT (nautique:(wqf=11)
      OR nautiques OR nautiqu OR nautiquement)) FILTER Ttext/html))
      4 results
