Abstract: A portable electronic device is disclosed comprising data processing means and a data repository containing: data records representative of locations relevant to or within a digital map; and data representative of an index associating words contained in the data records with the records in which those words appear. The device further comprises means for, in relation to a received search query including a search string, processing the search string to provide one or more search words; querying the index to identify data records containing the or each search word; and generating a rank for each of the one or more identified data records indicative of the relevance of each identified data record to the search query.

Abstract: A portable electronic device is disclosed comprising: data processing means; data repository containing data representative of a digital map; and display means. The device further comprises means for, in relation to data representative of a plurality locations relevant to the digital map, providing, on a representation of the digital map displayed on the display, for each of the locations, one of a plurality of different graphical user interface (GUI) elements characterised by different prominence levels to indicate the locations, wherein the prominence level of the GUI element used for each location is dependent on the level of detail at which the digital map is displayed and a deemed relevance of that location to a user query.

Abstract: A portable electronic device is disclosed comprising: data processing means; data repository containing data records representative of locations relevant to or within a digital map; and display means. The device further comprises means for monitoring a free text search string as it is input by a user of the device; querying the data repository for matching records and generating suggestions selectable by a user to adjust the search, based on the search string as it is input; displaying at least some of any matching records and suggestions on the display; and, in response to receipt of user input indicating a selection of a matching suggestion, adjusting the search accordingly.
