    document files. The acquisition process is called indexation.
    The resulting database can be big (roughly the size of the original
    document set), but it is not a document archive. Recoll can only display
    documents that still exist at the place from which they were indexed.
+   (Actually, there is a way to reconstruct a document from the information
+   in the database, but the result is not nice, as all formatting,
+   punctuation and capitalisation are lost).
    Recoll stores all internal data in Unicode UTF-8 format, and it can index
    files with different character sets, encodings, and languages into the
    same database. It has input filters for many document types.
 ...
    Recoll indexation takes place at discrete times. There is currently no
    interface to real time file modification monitors. The typical usage is to
    have a nightly indexation run programmed into your cron file.
+   +------------------------------------------------------------------------+
+   | Side note: there is nothing in Recoll and Xapian that would prevent    |
+   | interfacing with a real time file modification monitor, but this would |
+   | tend to consume significant system resources for dubious gain, because |
+   | you rarely need a full text search to find documents you just          |
+   | modified. recollindex -i can be used to add individual files to the    |
+   | index if you want to play with this, see the manual page.              |

    Recoll knows about quite a few different document types. The parameters
    for document types recognition and processing are set in configuration
    files Most file types, like HTML or word processing files, only hold one
    document. Some file types, like mail folder files can hold many
    individually indexed documents.

    After starting a search, a list of results will instantly be displayed in
    the main list window. Clicking on an entry will open an internal preview
    window for the document. Double-clicking will attempt to start an external
    viewer (have a look at the ~/.recoll/mimeconf file to see how these are

    By default, the document list is presented in order of relevance (how well
    the system estimates that the document matches the query). You can specify
    a different ordering by using the Tools / Sort parameters dialog.

 .2. Complex/advanced search

    It will let you search for documents of specific mime types (ie: only
    text/plain, or text/html or application/pdf etc...)
    It will let you restrict the search results to a subtree of the indexed
    area.
    Click on the Start Search button in the advanced search dialog to start
    the search. The button in the main window always performs a simple search.

-   The stemming language can be chosen among those that were specified in the
+   User interface parameters:
+     * Number of results in a result page
+     * Result list font: There is quite a lot of information shown in the
+       result list, and you may want to customise the font and/or font size.
+       The rest of the fonts used by Recoll are determined by your generic QT
+       config (try the qtconfig command.
+     * Html help browser: this will let you chose your the preferred browser
+       which will be started from the Help menu to read the user manual. You
+       can enter a simple name if the command is in your PATH, or browse for
+       a full pathname.
+     * Show document type icons in result list: icons in the result list can
+       be turned off. They take quite a lot of space and convey relatively

+       in the configuration file.
+     * Dynamically build abstracts: this decides if Recoll tries to build
+       document abstracts when displaying the result list. Abstracts are
+       constructed by taking context from the document information, around
+       the search terms. This can slow down result list display significantly
+       for big documents, and you may want to turn it off.
+     * Replace abstracts from documents: this decides if we should synthetize
+       and display an abstract in place of an explicit abstract found within
+       the document itself.

 ...
 .1.1. Prerequisites
    At the very least, you will need to download and install the xapian core
    package (Recoll currently uses version 0.9.2), and the qt runtime and
-   development packages (Recoll currently uses version 3.3.3).
+   development packages (Recoll development currently uses version 3.3.5, but
+   any 3.3 version is probably ok).
    You will most probably be able to find a binary package for qt for your
-   system. You may have to compile Xapian, but this is not difficult (if you
+   system. You may have to compile Xapian but this is not difficult (if you
    are using FreeBSD, there is a port).
    You may also need libiconv. Recoll currently uses version 1.9 (this should
    not be critical). On Linux systems, the iconv interface is part of libc
    and you should not need to do anything special.
