I add a field to a document using:
doc.add(Field.Text("path", "d=100&a=102"));
When I search for the document using "d=100&a=102" as the query using:
public static void main(String[] args){
String indexDir = args[0];
String queryStr = args[1];
System.out.println("indexDir = " + indexDir);
System.out.println("query = " + queryStr);
IndexSearcher searcher = new IndexSearcher(indexDir);
Term term = new Term("path", queryStr);
TermQuery query = new TermQuery(term);
Hits hits = searcher.search(query);
if (hits.length() == 0){
System.out.println("length = 0");
}
}
it returns nothing. If I use "SearchFiles" (the search example that
comes with the Lucene dist) I get:
Query: d=100&a=102
Exception in thread "main" org.apache.lucene.queryParser.TokenMgrError: Lexical error

How do I format the query in order to keep the parser satisfied? I
have tried the usual \-escaping of difficult characters, but that
doesn't work either. Is there a way to set which characters are
allowed in a query or something similar?
