About parse text to query
Text can be entered into the top most text field.
Clicking the “Parse input” button opens a display of the resulting parse. The resulting parse is also placed as a bracketed tree into the lower text field. This gives an opportunity to edit the parse tree. You can also forego making a parse and instead paste or type a bracketed tree into the lower text field. Clicking the “Query builder” button opens a query creation form.
Note that post-editing the parse will not be reflected in the displayed tree, but post-editing will be reflected in the content that is passed to the query creation form.
