AWS CloudSearch控制台提供不同的搜索结果

Question

In Aws console when I search "authority" it provide me the result which have the term "author" which is not at all feasible according to my search term. Is there any configuration problem.

Answer 1

This is because of stemming , which is a trick search engines use to try to return matches for the same root word. For example, a query for "cooking" should probably also match "cook", "cooked", etc. This is accomplished by indexing the word stems, and you can control the extent to which CloudSearch stems.

The default for English is full algorithmic stemming and what you have here is a case of that algorithm not returning the desired results. Your options are to turn down stemming to light or none , or to index this as a literal field rather than text (probably not what you want but I don't know much about your use case).

Here are the docs for Configuring Text Analysis Schemes and Text Processing in CloudSearch.
