First of all ensure that the page Property:Teaser exists and contains the following text:

[[has type::text]]

Then ensure that you have the latest version of SMW: only the latest version can search on Text properties.

Hello, I am trying to create semantic property just like that.

[[Teaser::some long text ..... ]]

But when I am doing the ask query like that

{{#ask: [[Teaser::+]]
| ?Teaser

the result is empty, until I reduce the length of [[Teaser::]] content.
And when I reduce the length of the teaser text I receive a link to the
new article instead of simple text. I beleive this is because too long
text can not be a title of an article and SMW tries to interpret it as.

How to say SMW that the Teaser property is just simple text, not an
article ?
