简单的基于文件的记录存储，具有用于Compact Framework和Silverlight的快速文本搜索功能

Question

I have a single table with lots of records (> 100k) that I need to be able to index and search on several text fields. The easiest searches will have the first part of the string specified (eg, LIKE 'ABC%' in SQL). The tougher searches will need to search for any substring within the text fields (eg, LIKE '%ABC%' in SQL).

I need to run on the Compact Framework. SQL Compact is a memory hog and overkill for my one table. Besides, I'd like to be able to run on Silverlight 4 eventually.

The file and indexes can be generated on the full .NET Framework and I only need read capability on the Compact Framework. My records are not especially large and can be expressed in fix length format.

I'm looking for some existing code or libraries to avoid having to write a file-based BTree implementation from scratch.

Answer 1

我最终选择了bplusdotnet 。

Answer 2

I would suggest System.Data.SQLite . It runs on the ADO.NET framework so It may not be what you're looking for but it supports the compact framework and may be lighter.

Take a look, hopefully it can suit your needs.
