Stopwords reference (Microsoft analyzers)
When text is indexed into Azure AI Search, it's processed by analyzers so it can be efficiently stored in a search index. During this lexical analysis process, language analyzers will remove stopwords specific to that language. Stopwords are non-essential words such as "the" or "an" that can be removed without compromising the lexical integrity of your content.
Stopword removal applies to all supported Lucene and Azure analyzers used in Azure AI Search.
This article lists the stopwords used by the Azure analyzer for each language.
For the stopword list for Lucene analyzers, see the Apache Lucene source code on GitHub.
Tip
To view the output of any given analyzer, call the Analyze Text REST API. This API is often helpful for debugging unexpected search results.
