[Building Sakai] Sakai Search Tool 2.6

[Zhen Qian]

Hi, Amy:

Collecting all search result and sort then outside search engine is one way to accomplish the task. However, doing so might introduce performance problem if the returning result is of big list.

Before Lucene 1.4, search results were only returned in descending relevance score  order. Sakai search tool is based on Lucence 2.9 (as of Sakai 2.7), so we are likely to leverage Lucene's inner sorting capabilities by doing the following steps:

1. Note that currently Sakai entities are indexed with the following fields populated: "siteid", "url", "tool", "title", "contents", "context", "subtype", "type", "id", "container", "reference", "digestCount". The field definition is inside SearchService.java. You can select subset of the list as search sort choices in Search tool, add the sort filter to search interface, I think it is the index.vm file, so that user can select the sort criteria. 

2. Modify search() inside SearchBeanImpl.java, so that you can set the sortName attribute to based user's selection of sort criteria;

3. Check search() inside BaseSearchServiceImpl.java, make sure the indexSorter field is setup correctly for sort. So if you are sorting based on title, the indexSorter should be constructed as new Sort("title").

And now you can search and sort!

HTH,

It should be possible to make a view that is a sortable table (though the paging will probably make this non trivial) I doubt though that the search tool actually knows enough about the returned results to make this feature really useful.
