full-text-search - 如何在开放式搜索服务器中使用同义词功能

Question

我正在尝试在 opensearchserver (http://open-search-server.com) 中使用同义词功能。我创建了一个列表，例如 ipod、i-pod、i pod => ipod、i-pod、i pod 它不工作。谁能告诉我如何使它与opensearchserver一起工作。

Answer 1

Here is the process to setup synonyms in OpenSearchServer.

1. Create the synonym list in the tab panel /Schema/synonyms. One line per group of equivalent words separated by commas:

Example:

ipod,i pod,epod,e pod
opensearchserver,open search server

2. Setup the analyzers to use the synonym list.

   • Go to the tab panel /Schema/Analyzers.
   • Edit the analyzer which will handle the synonyms. If you use the default schema template you should edit the StandardAnalyzer. Here is a screenshot capture which show the correct setup. To be multi-term aware, we have to add a shingle filter to build group of words. the synonym filter.

3. Reindex your data.

You can now search for ipod, i-pod, epod, e-pod, and find any ipod!

Remark: I removed the dash version (i-pod) because when you use the StandardAnalyzer, the dash are already ignored.
