Examples of org.apache.lucene.search.NumericRangeFilter

org.apache.lucene.search.NumericRangeFilter
A {@link Filter} that only accepts numeric values withina specified range. To use this, you must first index the numeric values using {@link NumericField} (expert: {@link NumericTokenStream}).
You create a new NumericRangeFilter with the static factory methods, eg:
```
 Filter f = NumericRangeFilter.newFloatRange("weight", 0.3f, 0.10f, true, true); 
```
accepts all documents whose float valued "weight" field ranges from 0.3 to 0.10, inclusive. See {@link NumericRangeQuery} for details on how Luceneindexes and searches numeric valued fields.
NOTE: This API is experimental and might change in incompatible ways in the next release. @since 2.9

        Query parsedQuery = queryParser.parse(filteredQuery(termQuery("name.first", "shay"), rangeFilter("age").from(23).to(54).includeLower(true).includeUpper(false))).query();
        // since age is automatically registered in data, we encode it as numeric
        assertThat(parsedQuery, instanceOf(FilteredQuery.class));
        Filter filter = ((FilteredQuery) parsedQuery).getFilter();
        assertThat(filter, instanceOf(NumericRangeFilter.class));
        NumericRangeFilter rangeFilter = (NumericRangeFilter) filter;
        assertThat(rangeFilter.getField(), equalTo("age"));
        assertThat(rangeFilter.getMin().intValue(), equalTo(23));
        assertThat(rangeFilter.getMax().intValue(), equalTo(54));
        assertThat(rangeFilter.includesMin(), equalTo(true));
        assertThat(rangeFilter.includesMax(), equalTo(false));
