Editing Desktop search (section)

=== Linux ===
There are a wide range of desktop search options for Linux users, depending upon the skill level of the user, their preference to use desktop tools which tightly integrate into their desktop environment, command-shell functionality (often with advanced scripting options), or browser-based users interfaces to locally running software.  In addition, many users create their own indexing from a variety of indexing packages (e.g. one which does extraction and indexing of PDF/DOC/DOCX/[[OpenDocument|ODT]] documents well, another search engine which works ith/ vcard, LDAP, and other directory/contact databases, as well as the conventional <code>find</code> and <code>locate</code> commands.

[[Ubuntu distribution|Ubuntu Linux]] didn't have desktop search until release [[Ubuntu version history#Ubuntu 7.04 (Feisty Fawn)|Feisty Fawn 7.04]]. Using [[Tracker (search software)|Tracker]]<ref>{{cite web|url=https://arstechnica.com/information-technology/2007/07/afirst-look-at-tracker-0-6-0/|title=A first look at Tracker 0.6.0|work=Ars Technica|date=26 July 2007|access-date=24 June 2015}}</ref> desktop search, the desktop search feature was very similar to Mac OS's AppleSearch and Sherlock. It not only featured the basic features of file format sorting and meta-data matching, but support for searching through emails and instant messages was added. In 2014 [[Recoll]]<ref>{{cite web|url=http://www.lesbonscomptes.com/recoll/usermanual/index.html#RCL.INDEXING|title=Recoll user manual|work=lesbonscomptes.com|access-date=24 June 2015}}</ref> was added to Linux distributions, working with other search programs such as Tracker and [[Beagle (software)|Beagle]] to provide efficient full text search. This greatly increased the types of queries and file types that Linux desktop searches could handle. A major advantage of Recoll is that it allows for greater customization of what is indexed; Recoll will index the entire hard disk by default, but can be made to index only selected directories, omitting directories that will never need to be searched.<ref>{{cite web|url=http://archive09.linux.com/feature/114283|title=Linux.com|access-date=24 June 2015}}</ref>

====[[openSUSE]]====
<!--TODO! Prior desktop search before KDE 3.5-->
Starting with [[KDE4]], the [[NEPOMUK (software)|NEPOMUK]] was introduced.  It provided the ability to index a wide range of desktop content, email, and use semantic web technologies (e.g. [[Resource Description Framework|RDF]]) to annotate the database.  The introduction faced a few glitches, much of which seemed to be based on the [[triplestore]].  Performance improved (at least for queries) by switching the backend to a stripped-down version of the [[Virtuoso Universal Server|Virtuoso]] Open Source Edition, however indexing remained a common user complaint.
Based on user feedback, the Nepomuk indexing and search has been replaced with the Baloo framework<ref>{{Cite web|url=https://community.kde.org/Baloo|title = Baloo - KDE Community Wiki}}</ref> based on [[Xapian]].<ref>{{cite web |url=http://www.opensuse.org/ |title=Home |website=opensuse.org}}</ref>
