text search -> error

After my answer I want to disable docman "Assign Custom Properties" and I have error

DB function failed with error number 1146
Table 'wedding.josw1_docman' doesn't exist SQL=SELECT SQL_CALC_FOUND_ROWS c.id AS id ,c.dmname as title ,c.published as state ,'' AS section ,IFNULL(cat.title, 'Static') AS category FROM josW1_docman AS c LEFT JOIN josW1_categories cat ON(c.catid = cat.id) WHERE 1 ORDER BY c.catid,c.dmname LIMIT 0, 20

Components Custom Properties > Utilities > Manage Content Elements
Uninstall ALL content elements in the right column

Hi

I try form the beginning, delete all joomla and install again with sample in data base
After joomla instalation add "customproperties_1.98.3.7_J15_build204"

1. I create/add position in "Manage Custom Properties"
2. Assign Custom Properties to articles
3. In modules "mod_cpsearch" I chose "search by text"

On website, when I try to search by List Box - everything is OK
but when I write text to label for "search by text" - Have just "Error"

When I Manage content elements-> add: content, docman; then
try to search by List Box - Have the same "Error"
write text to label for "search by text" - "Error"

What I'm doing wrong??
