In Korp you may perform quite advanced corpus serches.

!!!Searching with dependency relations

__Task:__ You want to search for all sentences with nouns in Illative that have the verb ''liikot'' as their dependency mother.

__Procedure:__ Write the string below into the ''CQP search'' interface in Korp.

The search string is as follows (here, it is put on 3 lines):

{{{
a:[msd="N.*.Ill"]
[]{0,10}
b:[lemma="liikot" & msd="V.*"]::a.dephead=b.ref
}}}

Explanation:

This group of commands 

{{{
[lemma="liikot" & msd="V.*"]
}}}

identifies the verb, by giving lemma and part of speech.

{{{
[]{0,10}
}}}

this gives zero or more whatever inbetween the two expressions

then the noun, its grammatical specification (singular or plural)
and its dependency relation.

{{{
[msd="N.*.Ill" & deprel="OBJ"]
}}}

Then you have to bind these groups to some variable names, 
the syntax is name:expression, as follows:

{{{
b:BUNDLE
a:BUNDLE
}}}

then you state the joint condition

{{{
::a.dephead=b.ref
}}}

which declares that the dependeny head of a shall be 
the ref value of b. In our context, the dependency
head of the illative noun shall be the value of
the verb ''liikot''.
