Hi all,
This is my first posting to this list. I am trying to figure out how to use
Lucy, using the instructions on this page:
http://incubator.apache.org/lucy/docs/perl/Lucy/Docs/Tutorial/BeyondSimple.html
I wrote the attached script, which works the first time I run it, but the
second time I run it, it gives me the following error:
---
rename from
'C:\Users\Desiletsa\Documents\eclipse_workspace\WeBiText\Spikes\lucy\schema.temp'
to
'C:\Users\Desiletsa\Documents\eclipse_workspace\WeBiText\Spikes\lucy\schema_1.json'
failed: File exists
lucy_Schema_write at
C:\Users\Desiletsa\AppData\Roaming\.cpanplus\5.12.3\build\Lucy-0.2.2\core\Lucy\Plan\Schema.c
line 410
at C:/Users/Desiletsa/Documents/eclipse_workspace/WeBiText/Spikes/try_Lucy.pl
line 32
---
If I delete the directory
C:/Users/Desiletsa/Documents/eclipse_workspace/WeBiText/Spikes/lucy, then I can
run the script again.
What am I doing wrong?
Thx.
