The query is ==> ID:0* This query returns all the documents, exactly 210.000 documents.If the user doesn´t specify any criterio in the user interface of searching, the server searchs all the documents.
Doing a prefix query (which ID:0* is) internally builds a BooleanQuery OR'ing all unique terms in the ID field that begin with a "0". The built in limit is 1,024 clauses in a BooleanQuery.
You will need to re-think your approach. If the goal is to return all documents, then use IndexReader to walk them. If the goal is to have a general user query expression where ID:0* would be entered you will need to account for that possibility with more system resources and bumping up the BooleanQuery limit or indexing differently so that there are no so many terms being put into the BooleanQuery. It is difficult to offer specific advice as I'm not sure what your use cases are.
