_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 analysis
|
|
|
|
{es} performs text analysis when indexing or searching <<text,`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 {es} to:
|
|
|
|
* Build a search engine
|
|
* Mine unstructured data
|
|
* Fine-tune search for a specific language
|
|
* Perform lexicographic or linguistic research
|
