Hi Bing, Wow! That was an information-rich post. Using Lucene goes way beyond my usual minimalist approach to feature implementation. You must have some use cases with a lot of attribute data. So far, I haven't seen the need for indexing in my own work, and I would hate to pay the memory/time price for a tool that I would use only occasionally.
Supporting the Editable and Selectable layer settings in plugins is a judgment call. Generally, I try to support them, but for some tools it makes sense to ignore the setting. In the case of a search tool, I would think the Selectable setting should be honored. This would be useful, for instance, when you have temporary duplicate layers that you wish to exclude from the search. I like the approach Michael took in the Simple Query plugin. Results can be displayed in the Feature Info table if selection is impractical. Also, I think that just because something is hidden due to a scale range, it shouldn't be exempt from selection. I'm not sure what happens with the selection handles though. thanks, Larry On Tue, Dec 30, 2008 at 12:24 AM, Bing Ran <bing_...@hotmail.com> wrote: > Hi, Larry, > > I have implemented a Lucene based global attribute search for my > application.
