Short Desc:- I need to develop the links to allow the user to narrow down or broaden the search results. How can I achieve it? I have thought of the possible algo for it which is given in the end.
Detailed Desc. with example:- Suppose I have 3 fields that are indexed and searchable namely vehicletype, vehiclebrand, vehiclemodel. The hierarchy is as follows.. there may be many vehicletypes.. each vehicletype may have many vehiclebrands.. each vehiclebrand may have many models Suppose there are 3 possible values of vehicletype: car,truck,bike brand for car might be toyota,lexus,ford,honda etc brand for bike might be suzuki,honda etc models are like modelA, modelB,modelC etc The person searches for "something vehiclebrand:lexus". Some results will come. I want to give the user the ability to narrow down/ broaden the results depending upon the results recieved. Suppose 5 modelA come, 3 modelB come in the results. I will like to give the user a link to narrow down on one of these models, so essentially making the search query as "something vehiclebrand:lexus vehiclebrand:modelA" or "something vehiclebrand:lexus vehiclebrand:modelB" Also to allow him to broaden the search results to all cars rather than just lexus cars, so suggesting the query "something vehicletype:car" or the broadest query "something" Again, if the user searches for this broadest query "something", we will get suggestion to narrow down either to vehicletype car or truck or bike or maybe even to vehiclebrand:lexus Possible algo:- Traverse all the results, read all the field values of the indexfields for each result and do a frequency analysis. On the values of the indexfields. Does anything exist which can help me? What are the classes I need to look at? -- www.jkg.in | http://www.jkg.in/contact-me/ Jayant Kr.
