The Query Fragments window

Selecting the ToolsQuery Fragments menu entry will open a window with radio- and check-buttons which can be used to filter the current query with user-defined query language fragments. This can be useful if you have frequent reusable selectors, not covered by the standard category selectors, for example, filtering on alternate directories, or searching just one category of files. In practise, the query fragments are joined to the current query as an AND clause.

The contents of the window are entirely customizable, and defined by the contents of a XML text file, named fragment-buttons.xml and which will be looked for in the current index configuration directory. The sample file distributed with Recoll contains a number of example filters. This will be automatically copied to the configuration directory if the file does not exist in there (e.g. ~/.recoll/fragment-buttons.xml under Linux and Mac OS, $HOME/AppData/Local/Recoll for Windows). Editing the copy will allow you to configure the tool for your needs .


The fragment-buttons.xml file was named fragbuts.xml up to Recoll version 1.31.0. This was deemed too close to offensive for native English speakers, so that the file was renamed. An existing fragbuts.xml will still be used if fragment-buttons.xml does not exist. No automatic renaming will be performed.

Here follows an example:

<?xml version="1.0" encoding="UTF-8"?>
<fragbuttons version="1.0">

    <!-- Actually useful: toggle Web queue results inclusion -->
      <label>Include Web Results</label>

      <label>Exclude Web Results</label>

      <label>Only Web Results</label>



      <label>Example: Year 2010</label>

      <label>Example: c++ files</label>
      <frag>ext:cpp OR ext:cxx</frag>

      <label>Example: My Great Directory</label>



Each radiobuttons or buttons section defines a line of checkbuttons or radiobuttons inside the window. Any number of buttons can be selected, but the radiobuttons in a line are exclusive.

Each fragbutton section defines the label for a button, and the Query Language fragment which will be added (as an AND filter) before performing the query if the button is active.

The only thing that you need to know about XML for editing this file is that any opening tag like <label> needs to be matched by a closing tag after the value: </label>.

You will normally edit the file with a regular text editor, like, e.g. vi or notepad. Double-clicking the file in a file manager may not work, because this usually opens it in a WEB browser, which will not let you modify the contents.
