hi,

are you able to copy/paste here your current implementation of the GetValue method?

tnx

NEW POST: Creating custom crawled properties

gdeckler — Mon, 09 Jun 2008 21:30:28 GMT

Has anyone been successful in creating crawled properties in their protocol handler that go into a custom category versus the default "SharePoint" category.

I have successfully created a small separate console application that creates my own custom category and my own custom crawled properties. I have also successfully created a protocol handler that when content is crawled automatically adds my own discovered crawled properties. The problem I am currently having is that my protocol handler custom crawled properties go into a default crawled property category of "SharePoint". I would rather have them go into the custom category I have created but I have not been able to figure out how to get that accomplished.

I have found Microsoft documentation indicating that the combination of the Protocol Handler and iFilter determine which category a crawled property goes into but I have not been able to find the code that makes this happen.

Has anyone been able to accomplish this?

I have a separate config application that creates these properties, but I think you can also run it on install.

NEW POST: Does anybody have a complete sample that works with db or web-services?

Hi all,

I have a solution with custom protocol handler that indexes business objects from web-services. And I can't finish it because some parts of this PH I can't complete.

I would be very much obliged to you if someone give me complete PH for some fake webservices (like WSOrders) or other sample that works.

Thanks in advance.

Where would you run this block of code? In the Accessor.Init method or does it need to be run only once on install?

NEW POST: Link-Based Protocol Handler

Hi all -- what would the necessary changes be to switch the C# Protocol Handler from a directory-based protocol handler to a link-based one?

CREATED ISSUE: Protocol Handler registry path

turnerjos — Fri, 09 May 2008 15:11:13 GMT

Documentation should be updated with the registry path that MOSS 2007 uses for registering protocol handlers: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office Server\12.0\Search\Setup\ProtocolHandlers

Hi Cipri,

No I haven't noticed but I haven't had any metrics to compare to either. I've been testing the Protocol Handler with indexing simple text files which is fast. I suspect it would have to do with your IFilters (PDF is slow).

Hi John,

I tried to install it on a 64-bit platform as well. From what I have seen it is much slower than on a 32-bit server. Don't know if this is because of our customization/hardware or maybe IFilters, but just wanted to ask you: have you notice and performance issues after you migrated on a 64-bit server?

Thanks,
Cipri

NEW POST: incremental crawl

lazedo — Tue, 18 Mar 2008 10:12:58 GMT

hi,

i'm indexing a database table with millions of records, and the incremental crawl is basicaly a full crawl,

i got it working and here's how i did it.

Prepare an auxiliary table
1) create a table with the PK and lastupdate of the table i want to index
2) created an aditional column and called it "folder"
3) populated the new table and filled the "folder" column randomly with 100 diferent values

when i crawl the "root" folder, i enumerate the the diferent "folder" values and get max(lastupdate)
--> SELECT FOLDER, MAX(LAST_UPDATE) GROUP BY FOLDER

on GetChunk, instead of creating a PIDGTHRDIRLINK and using GetText to get the link, i used PIDGTHRDIRLINK_WITHTIME and used GetValue to return a variant array with the link and last modification of that link.

this way, on incremental crawls, the only "folder" (group of records) that gets indexed again are the ones who belong to a "folder" that as at least one record changed. the more folders you have, fewer records are indexed.

cheers

NEW POST: Order of how properties are stored

Ludvig — Mon, 17 Mar 2008 10:04:47 GMT

I have created a protocol handler with your code and it works good.

Have one question thou:
If I add values to properties in the ArrayList of properties, will they be overwritten by the properties that the iFilter will set?
Or is there a way to be able to retrieve the values from iFilter before they are stored in the index to be able change them afterwards.

use the guidgen.exe tool and after you got your gui string split it(see bellow) and then call :

new Guid(0x@@@@@@@, 0x@@@@, 0x@@@@, 0x@@, 0x@@, 0x@@, 0x@@, 0x@@, 0x@@, 0x@@, 0x@@);

hope this helps,

NEW POST: SharePoint Indexer 64-bit

john_meilleur — Thu, 13 Mar 2008 16:08:37 GMT

Hi,

Well I've got it working but I need to rebuild in a clean environment to determine exactly which steps required.

I found that I needed to use the regasm from the 64 bit framework and I also registered the assembly in the GAC so the DLL could be found.

Needless to say, I have successfully run the protocol handler.

hi there,

i haven't but i have seen a similar error(or maybe similar) on a 32-bit environment as well. try to check that the ms search service runs under an user with local admin rights.

and also, please let us know if you succeeded or not.

cheers,

Has anybody had success with installing the Protocol Handler in a 64-bit environment. When I attempt to crawl it returns an error message saying it can't find the handler.

NEW POST: Full framework?

Ludvig — Sat, 08 Mar 2008 09:41:04 GMT

Hi!
I wonder if your framework covers all features that exists if you create a protocol handler in c++? Is there any features missing?
I specially wonder if it has full support for ACL?

I'm planing to create a connector that fetches indexed information from MOSS through the Search API. This because I need to change/add properties to what is indexed and I haven't found any other way then to take out everything in the index and then change properties and then feed the information to a new collection back in MOSS. Hopfully I will be able to retrive ACL information through the API and then feed it back through the connector. If I can't get the acl I will use the sharepoint api to get the full page and there get the acl and then feed it in through the connector.

Do you think this is possible with your connector?
