– If you need to modify the query, you can modify the query either from the  Query Builder or from the Query Tree. – When you want to add the built query to a certain node in the Query Tree,  select the query node in the Query Tree and issue the query with the  search operator. 4. Repeat steps 1 – 3 to build the query that you want. You can use the Query  Tree to help you build the query. 5. After you complete the query building, save the query for reuse in the future,  such as for document export or to build another query. Consider an example where a specific document contains keywords that you  want to use to find similar information. The document contains information about  the “lemon tea” product. Select the document in the Documents view, and open  the Query Builder window, as shown in Figure 5-40 on page 126. After you open the Query Builder, a preview of the selected document is  displayed in the Document preview area or the Facet list area. Select a query  type from the drop-down list, and drag the keyword in the document.  In this example, we select  Facet query  as the query type, and select  General  Noun: package  from the Facet list. We select another  General Noun: pack  from  the Facet list, as shown in Figure 5-44 on page 130. Building and issuing a query Selecting a document and opening the Query Builder  Chapter 5.
