Text analysisedit
Text analysis is the process of converting unstructured text, like the body of an email or a product description, into a structured format that’s optimized for search.
When to configure text analysisedit
Elasticsearch performs text analysis when indexing or searching text
fields.
If your index doesn’t contain text
fields, no further setup is needed; you can
skip the pages in this section.
However, if you use text
fields or your text searches aren’t returning results
as expected, configuring text analysis can often help. You should also look into
analysis configuration if you’re using Elasticsearch to:
- Build a search engine
- Mine unstructured data
- Fine-tune search for a specific language
- Perform lexicographic or linguistic research
