it should still fix some issue I was trying to create a search where you could search by typing some part of the name. But when the search input is empty it shows everyone in the table. I tried to write the SQL to select * when the search input is = to " "(empty) and to select * that has at least part of the sentence when the search as 1 character or more, but everytime if i write something it works, but when the search input is empty any row is selected. My code is: , Assuming you are using SQL Server:
code :
WHERE [nome] LIKE '%' + coalesce(@search, '') + '%'
WHERE [nome] LIKE '%' + @search + '%' AND @search <> ''

hope this fix your issue Google does not have access to your database, only your web pages. It regularly crawls your web pages and indexes them, just like it would for its own search results. The only difference is it serves up results specific to your website to your website.

Does that help It looks like science direct uses a variable that has a unique value for each search (md5=9e299e9289462d7805ab0a5dcc9cff5c in your example). This value changes even if you do the same search.
I haven't done any detailed investigations, but if they do some checks on their side (such as checking cookies, ip address etc.) it can be difficult, if not impossible to do.

I wish this helpful for you Ok, I have found it!
Roo 1.1.5 calls populate methods on every CRUD request even before actual controller method is called. Populate methods fetches all entries from db, which makes it a huge overload, huge enough to make web app quite unusable and look bad in front of your managers :(

hope this fix your issue Shift-Shift shows a popup with occurrences of the string you've entered in names of files, classes, symbols and actions. Shift-Command-O shows a popup with occurrences of the same string only in names of files. Same task, same UI (in recent IJ/AS versions) more narrow filter.
