0.01 Mon Apr 23 03:37:59 2001

• original version; created by h2xs 1.20 with options

  -XA -n Freq 0.16 Tue Jan 25 19:04:25 PST 2005

• Complete rewrite. Pure perl, with arbitrarily complex sequence and alternation queries, proximity searches, sentence-boundary indexing.

0.17 Thu Jan 27 16:04:25 PST 2005

• Documentation corrections; added ABSTRACT; isr closure update; removed dependency on latest perl; added dependency on FileHandle;

0.19 Tue Feb 1 15:20:48 PST 2005

• Added Inline'd sum_to_pos for both speed and memory savings.

0.20 Fri Feb 4 12:51:32 PST 2005

• fixed bug in next_integer_length causing infinite loop; changed to older module file layout to avoid conflict with Inline::MakeMaker. Annoyingly this produces a recompile on every make, even when just Perl code has changed

0.21 Mon Feb 7 19:05:32 PST 2005

• bug in sum_to_pos made premature end to px; bug in isr_align_match closures gave false matches with inappropriate px

0.22 Thu Feb 10 13:49:41 PST 2005

• changed DX underlying structure to ber-string instead of Perl array, added sum_to_doc inlined C function to process it. Gives huge memory savings and 2x search speedup; fixed bug in and-matcher logic
