Numeric range search Leave feedback
Numeric range search or numerical search allows you to search in documents any integer numbers in the range from 0 to 9223372036854775807 (Long.MAX_VALUE). Please note that the number in the text must not be separated by spaces, otherwise it will already be several numbers. A search query of this type is specified as follows:
number ~~ number
The example below demonstrates the numeric range search in text and object forms.
String indexFolder = "c:\\MyIndex\\";
String documentsFolder = "c:\\MyDocuments\\";
// Creating an index in the specified folder
Index index = new Index(indexFolder);
// Indexing documents from the specified folder
index.add(documentsFolder);
// Search with text query
SearchResult result1 = index.search("500 ~~ 600");
// Search with object query
SearchQuery query2 = SearchQuery.createNumericRangeQuery(500, 600);
SearchResult result2 = index.search(query2);
