Problems solved by technology

[0011] Therefore, the two operations of inputting search text and specifying logical operators must be performed, which becomes a burden on the operation
Especially in navigation devices where the scope of search objects is limited to specific buildings or locations, specifying logical operators will reduce operational efficiency

Embodiment Construction

[0042] (1) Outline of Embodiment

[0043] The navigation device 1 can pass the attribute tag 87 ( Figure 2A ) to designate any one of the attributes of "name", "address" and "category" and enter a keyword.

[0044] The navigation device 1 sets retrieval conditions by logical AND for keywords belonging to different attributes, and for keywords belonging to the same attribute, when it is a subordinate relationship, the retrieval condition is set by logical AND, when it is not an affiliation relationship, Set search conditions by logical OR.

[0045] Thus, when a keyword is input, the navigation apparatus 1 can select an appropriate logical operator based on an attribute, and can automatically set a search condition.

[0046] Furthermore, the navigation device 1 displays the approximate number of the number of search objects in the number area 86 while the search is being performed.

[0047] In the case where the search condition is formed by logical AND, the maximum number o...

Abstract

In a navigation device, three categories, Name, Address, and Genre, can be designated one at a time by using category tabs. Keywords can be input after the category is designated. Logical multiplication is set as a search condition when the keywords belong to different categories. When the keywords belong to the same category, the search condition is set to logical multiplication if the keywords are in a hierarchical relationship and is set to logical addition if the keywords are not in a hierarchical relationship. Where the search condition is logical multiplication, the maximum number of search results is the number of search objects for the keyword that has the fewest search objects, so that number is displayed. Where the search condition is logical addition, the maximum number of search results is the sum of the numbers of the search objects for each of the keywords, so that number is displayed.

Description

technical field [0001] The present invention relates to a retrieval device, a navigation device and a retrieval method, for example, it relates to supporting the input of retrieval words. Background technique [0002] In recent years, a technique of guiding a vehicle using a navigation device has become popular. [0003] The navigation device has the following functions, that is, the function of searching the route from the departure point to the destination, the function of detecting the position of the own vehicle using sensors such as GPS (Global Positioning System: Global Positioning System) satellites and gyroscopes, and the function of displaying the location of the vehicle on the map. A function to display the route to the destination and the current position of the own vehicle, etc. [0004] In general, in a navigation device, as in the technical solution proposed in Patent Document 1, a plurality of items (pronunciation, category, address, etc.) Next, narrow down...
