The xadump command is a low-level access and diagnostic tool for a Xapian index as organized by the Recoll indexer. The index directory to be used is specified with option -d.

Options -D, -X, -T and -r take a single docid argument specified with option -i. -D displays the document data record. -X deletes all index data for the document. -T prints the term list for the document. Without a docid argument, this option will list the whole index term list. -f can be set to precede each term with its occurrence count (only if no docid is specified). -n can be set to omit the enclosing brackets. -l can be set to skip prefixed terms. -r prints the document text as reconstructed from index data.

When option -x is set, terms are printed with each character separated by a space, which can be useful to check some encoding issues.

Options -E, -F and -P all need a term argument, specified with -t <term>. -E performs a term existence test. -F retrieves the term frequency for the given term. -P displays the postings for the given term.

With option -q, xadump performs a simple AND query on the index, using the given term arguments.
