Each searchable document provides provides a document type in its meta +data and if a corresponding handler is found, it can be searched. + +Search handlers are described by a desktop file which is put in the khelpcenter +app directory in a "searchhandlers" directory. The desktop file contains the +information about which document types the handler covers, how to do a search +query and how to create a search index. + +A search handler has to provide a command line tool based interface. There has +to be a command to do a query and, if previous creation of an index is required, +a command to create a search index. The search commands returns its results as +HTML on stdout. + + +Search Query +------------ + +KHelpcenter reads the command to execute for submitting a search query from the +search handler's desktop file ("SearchCommand"). The search command can contain +some symbols which are replaced by KHelpcenter with the data for the concrete +search request: + +%i Identifier of document (usually the name of the document's desktop file) +%w Words to be searched for +%o Operation for combining multiple search words. Allowed values: "and" and + "or". +%m Maximum number of results +%d Directory containing search indices + +Search Query Result +------------------- + +The result has to be returned as HTML page. The content of the <body> tag will +be extracted and inserted in the search results page. If there is no body tag, +the complete result text will be inserted. + + +Building a Search Index +----------------------- + +KHelpcenter reads the command to build a search index from the search handler's +desktop file ("IndexCommand"). The indexing command can contain some symbols +which are replaced by KHelpcenter with the data for the concrete index creation +call: + +%i Identifier of document (usually the name of the document's desktop file) +%d Directory containing search indices +%p Path to document to be indexed + +Index Creation Result +--------------------- + +As result of the indexing command an index is created in the directory specified +by KHelpcenter. The format and structure of the index is handler-specific. When +index creation is finished the indexing command has to create a special file +with the name "<identifier>.exists", where <identifier> has to have the value +passed by the %i symbol. This file indicates the existance of the index. |
