search for queries utilizing a specific field

The "Find Object References - Record Field" feature in Application Designer, 
when used to search for queries utilizing a specific field (i.e. "EMPL_STATUS"), 
is not accurate because it returns queries that do NOT use the field (this 
behavior is caused by adding a field to a query and then removing it -- the 
field remains in the PSQRYFIELD table, so it shows up on the object references 
search).
Furthermore, the "find object references" feature is of limited use since it 
is not clear if the field is merely in the select columns, or actually in the 
"where" criteria.
Use this SQL code for more precise results ...
1. The COLUMNNUM column indicates the field is used in the Select if the value > 0
2. The USECOUNT column indicates the field is used in the Criteria if the value > 0

3. To exclude delivered queries, use the LIKE command (i.e. this codes searches only "ABC" queries)


SELECT QRYNAME "QUERY NAME",
       DECODE(COLUMNNUM, 0, 'NO', 'YES') "SELECT",
       DECODE(USECOUNT, 0, 'NO', 'YES') "CRITERIA"
  FROM PSQRYFIELD
 WHERE FIELDNAME = 'EMPL_STATUS'
   AND QRYNAME LIKE 'ABC%'
 ORDER BY QRYNAME


### Java Elasticsearch Prefix Query on Array Field Example In order to perform a `prefix` query on an array type field using the Java High Level REST Client, one can construct a search request with specific query DSL that targets elements within an array. The following demonstrates how this is achieved: ```java import org.elasticsearch.action.search.SearchRequest; import org.elasticsearch.action.search.SearchResponse; import org.elasticsearch.client.RequestOptions; import org.elasticsearch.client.RestHighLevelClient; import org.elasticsearch.index.query.QueryBuilders; import org.elasticsearch.search.builder.SearchSourceBuilder; public class EsPrefixQueryExample { private static final RestHighLevelClient client = new RestHighLevelClient(/* configuration */); public void executeSearch() throws Exception { SearchRequest searchRequest = new SearchRequest("index_name"); // Building the prefix query targeting an element inside an array. SearchSourceBuilder sourceBuilder = new SearchSourceBuilder(); sourceBuilder.query(QueryBuilders.prefixQuery("array_field", "pre")); searchRequest.source(sourceBuilder); SearchResponse response = client.search(searchRequest, RequestOptions.DEFAULT); System.out.println(response.toString()); } } ``` The above snippet shows constructing a simple prefix query against `"array_field"` where any string starting with `"pre"` will match as long as it exists in the indexed documents' arrays. For more complex scenarios or when needing to ensure only complete matches of prefixes across all items in an array are returned, consider utilizing nested queries combined with bool queries and term queries depending upon mapping types and requirements[^1].
