 Suggests possible ways to complete a search query as you type and shows suggestions in their order of relevance. 

 

Key Advantages:

• Increase the speed in which users can formulate their queries.
• Comes with a vast knowledge base of possible phrases, no reference database needed.

 

 Behind the scenes: The Autocomplete feature generates suggestions from the Keyphraseness file specified in the configuration file. The algorithm uses the Patricia Trie data structure designed for rapid search of phrases starting with the same prefix. In addition, the Keyphraseness values (See Section 2.1) help to rank the phrases in their order of likelihood of being a useful suggestion.

Parameters:

Query – Any part of the query that needs to be completed.

Number of results – Number of completion suggestions to return by the method.

 

Configuration: It is possible that the Keyphraseness file is not an appropriate input for the suggestions. This file can be replaced by any other list of phrases with the associated scores if such are available. For example, one could supply a histogram of logged queries used to search a company’s website. The format of the file should be the following:

pingar api,1,8
pingar software,1,10
…

With no spaces after the comma, the first digit representing the Keyphraseness (a default value of 1 can be used for all phrases) and the second digit the frequency of that query in the histogram.
