Examples of NumericTokenStream

org.apache.lucene.analysis.NumericTokenStream
Expert: This class provides a {@link TokenStream}for indexing numeric values that can be used by {@link NumericRangeQuery} or {@link NumericRangeFilter}.
Note that for simple usage, {@link NumericField} isrecommended. {@link NumericField} disables norms andterm freqs, as they are not usually needed during searching. If you need to change these settings, you should use this class.
See {@link NumericField} for capabilities of fieldsindexed numerically.

Here's an example usage, for an int field:
```
 Field field = new Field(name, new NumericTokenStream(precisionStep).setIntValue(value)); field.setOmitNorms(true); field.setOmitTermFreqAndPositions(true); document.add(field); 
```
For optimal performance, re-use the TokenStream and Field instance for more than one document:
```
 NumericTokenStream stream = new NumericTokenStream(precisionStep); Field field = new Field(name, stream); field.setOmitNorms(true); field.setOmitTermFreqAndPositions(true); Document document = new Document(); document.add(field); for(all documents) { stream.setIntValue(value) writer.addDocument(document); } 
```
This stream is not intended to be used in analyzers; it's more for iterating the different precisions during indexing a specific numeric value.

NOTE: as token streams are only consumed once the document is added to the index, if you index more than one numeric field, use a separate NumericTokenStream instance for each.

See {@link NumericRangeQuery} for more details on theprecisionStep parameter as well as how numeric fields work under the hood.

NOTE: This API is experimental and might change in incompatible ways in the next release. @since 2.9
