Searching in a Tree-Navigation

[Donny Donselm]

Hello Everyone,

i am currently researching with what way i can best develop a
tree-hierarchy with a search function.

So what i got:
I got a hierarchical database with 13.000 datafields.
Currently i ordered it like the following:

Every ITEM has an ID, and a PRE_ID (only the ROOT which has the ID 0 has
no PRE_ID).

So now there are different levels. For instance all ITEMS on level 1
reference to the root with PRE_ID = 0.

Every ITEM on level 2 references an item on level 1 etc.etc..

If you think about it, at the end you got a tree starting with a root.

Now what i would like to do would be to represent this TREE as some kind
of Tree-Navigation. Meaning - a multi level Tree- navigation (something
like this):

http://jquery-plugins.bassistance.de/treeview/demo/

Ok - now the bigger Problem. Since i got 13.000 Knots - i want to be
able to search in the navigation.

Every knot has a description. So i want to add a field and if I for
instance enter the term "blue" the tree should change based on the
search term.

So, the way i want to change the tree is that a term is found, the tree
should open the specific branch everywhere where the term can be found.

I guess creating the navigation might work with the given jquery-pluin.
The big problem i see is combining it with a search and a way how to
display the results.

At the moment i am not stuck with anything - i can even change the way i
handle the data (the IDs). Just the reference structure need to be
somehow conserved. Does anyone have any suggestions? I mean i guess i
could program it by myself (tons of work) - but i really would prefere
an easier solution - meaning an already created plugin or similar stuff.

So far - could not find anything in the internet.

Aprreciate any help!

Bye!

Take a look at https://github.com/collectiveidea/awesome_nested_set

It is a robust gem that would make traversing your nested tree structure a bit easier.
