× The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.

That's interesting Frank. It seems like your speed advantage is as simple as making the server do all the work at once rather than passing requests and results back and forth like FNDSTRPDM does. I've not tried to use the search yet, due to pressure from on high, but I was wondering whether your system handles searches from multiple jobs and/or users at the same time?

Edmund,

the search routines are implemented in RPG IV. There is a service program FNDSTR in library ISPHERE which is doing this stuff. This service program will be called by the iSphere client. But this is not the reason for the high performance. The secret is the way the search request will be transferred from the iSphere client to the iSphere server and the way the iSphere client receives the search results from the iSphere server. If you start the search for a member filter the iSphere client resolves the member filter. Then with an SQL INSERT the members to search for are transferred to the iSphere server to table FNDSTRI in library ISPHERE. For 500 members one SQL INSERT will be generated. If you have 2000 members to search there will be 4 SQL INSERTs generated. The SQL INSERT will be executed RAPIDLY. After this the service program FNDSTR is doing the search and places the search results into table FNDSTRO in library ISPHERE. After this the iSphere client receives the search results from table FNDSTRO with an SQL SELECT. This is also be done rapidly.

The iSphere project is open source inclusive the host stuff. The library ISPHERE contains all sources. For those ones who want to use the iSphere search for their own projects there is an example in member DEMO in source file QRPGLESRC in library ISPHERE which illustrates the use of the service program FNSTR.

Frank,
I am just curious, you don't have to tell me any of your trade secrets if you don't want. But what are you doing to get the performance gains? Feel free to tell me that it is classified information :-)

Peter,

the first time after an IPL using iSphere Power Search can take a little more time. But after the second time you should see the improvement.

On my box i search a member filter containing 637 members. iSphere Power Search takes 3 seconds and the original RSE Search takes 185 seconds.

For the binding directory issue i think you have deleted the ISPHERE data area in library QGPL containing the release of the installed OS. Take a look at the manual.

Frank

Hi Frank,

After the re-install, the power search is working.

However, I did a speed comparison between the standard WDSCi search and the power search, and failed to see any major improvement.

The search was on a source file filter (13 files in 4 libraries), resulting in 3 hits.

Native "find string": 80 seconds
iSphere power search: 52 seconds

Unless I'm doing something wrong, this isn't quite "60 times faster", or can one only achieve such improvements on much broader searches?

Also, "edit binding directory" always gives me an empty list, even though there are entries when using 5250.

Met vriendelijke groeten / Best regards,

Peter,

there have been another bug, which i have fixed. Please download and install iSphere once again. Let me know if it works now.

Frank
