# Field Analyzer - Introduction

Field Analyzer LimitsNot all field analyzer functions are supported for all field and data types Processing TimeDepending on the size and type of data being analyzed, Analyzer functions can take some time to run.   Continuous Strings of millions of records may take some minutes.  
**TODO: How to add analyzer indexing to load scripts**

## Available Field Analyzer functions:

Supported Data and FieldTypes:

- String (Continuous and Discrete),
- Integer (Discrete),
- Double (Discrete),
- Date (Discrete)

| Analyzer Function | Description |
| --- | --- |
| CharDiscrete | Counts how many times the character appears in the list of discrete values |
| CharRecords | Counts the number of records that contain the character |
| CharOccurrences | Counts the total number of occurrences of the character in the field |
| CharSummary | Calculates CharRecords and CharOccurrences and displays in same grid |
| SLenDiscrete | Calculates the number of field values that have a particular length |
| SLenRecords | Calculates the number of records that have a particular length |
| WordsDiscrete | Counts the number of field values that have a particular word length |
| WordsRecords | Counts the number of records that have a particular word length |
