Hi all,

i am new here and from Germany, so please be patient with my english Smile

We try to implement a fulltext search with a ranking but we are not able to set Oracle Text to our needs. So i will discribe what we want to do and it would be great if u could tell us, if this is possible and how.

There are some tables like:
Table People
ID      Givenname            Surename      
------- -------------------- ----------------
1       Hans                 Meier
2       Frauke               Huber
3       Werner               Krause-Meier

Table Adress
ID      Street               Street_Number
------- -------------------- ----------------
1       Hauptstr             4
2       Lukas-Meier-Str      23
3       Bahnhofstr           11

Table People_Adress
People_ID     Street_ID
------------- --------------
1             2
2             1
3             3

Now we want to search "Meier".

The result should be like:
Ranking Result
------- -------------------------
10      Hans Meier Lukas-Meier-Str 23        // ranking 10 because "Meier" is found in People and Adress
5       Werner Krause-Meier Bahnhofstr 11    // ranking 6 because "Meier" is only found in People

In real, there are more tables and columns per table and of course dependencies. Before we get deeper, we need to know if this is possible with Oracle Text.
