Searching and indexing example APP
2+
**********************************
3+
4+
Main.js and Main.html - HTML/JS client side
5+
Server.py - HTTP Server and server side processing via. REST API
6+
7+
Configuration
8+
*************
9+
10+
Open "Server.py" and change the COOL and Solr server URL ("coolServerUrl" and "solrServerUrl") if they are different
11+
than localhost and default ports.
12+
13+
The "documentPath" constant is the root location of the documents (relative where Server.py was started).
14+
15+
The "solrCollectionName" constant is the collection name where Solr should store the indices.
16+
17+
The "coolInstance" is the URL to the COOL instance, which is used to open a document.
18+
19+
The collection needs to be created in Solr, if it doesn't yet exists with (from Solr root):
20+
./bin/solr create -c <collection name>
21+
22+
For exmaple:
23+
./bin/solr create -c documents
24+
25+
HTTP Server
26+
***********
27+
28+
Run http server on locally with:
29+
"python Server.py 8000 127.0.0.1"
30+
31+
Then connect from the web browser to "http::/localhost:8000"
32+
33+
First time - run "Re-Index Documents" or nothing will be found
