Detailed Description

Before the search engine can be used, one has to instantiate at least a QHelpEngineCore object that needs to be passed to the search engines constructor. This is required as the search engine needs to be connected to the help engines setupFinished() signal to know when it can start to index documentation.

After starting the indexing process the signal indexingStarted() is emitted and on the end of the indexing process the indexingFinished() is emitted. To stop the indexing one can call cancelIndexing() .

When the indexing process has finished, the search engine can be used to search through the index for a given term using the search() function. When the search input is passed to the search engine, the searchingStarted() signal is emitted. When the search finishes, the searchingFinished() signal is emitted. The search process can be stopped by calling cancelSearching() .

If the search succeeds, searchingFinished() is called with the search result count to fetch the search results from the search engine. Calling the searchResults() function with a range returns a list of QHelpSearchResult objects within the range. The results consist of the document title and URL, as well as a snippet from the document that contains the best match for the search input.

To display the given search results use the QHelpSearchResultWidget or build up your own one if you need more advanced functionality. Note that the QHelpSearchResultWidget can not be instantiated directly, you must retrieve the widget from the search engine in use as all connections will be established for you by the widget itself.

class QHelpSearchEngine(helpEngine[, parent=None])
param parent

QObject

param helpEngine

QHelpEngineCore

Constructs a new search engine with the given parent . The search engine uses the given helpEngine to access the documentation that needs to be indexed. The QHelpEngine ‘s setupFinished() signal is automatically connected to the QHelpSearchEngine ‘s indexing function, so that new documentation will be indexed after the signal is emitted.
