If you are using SOLR you must take account of the fact that there will be a delay (however short) between uploading content and being able to search for it.

There are a couple of approaches.
a) Don't use search to find a document you just uploaded, use one of the other APIs such as a lookup by noderef or list the contents of a folder. That's how Alfresco Share works.
b) Don't use SOLR, use the in transaction Lucene index subsystem instead.

i have to do search on metadata and i have to show document list on the basis of that metadata.
Hence a search on folder or noderef will not work.

So that means i can not use solr subsystem in this scenario
Isn't there any other way to resolve this problem without dropping solr?

mroger really thanks for your clarifications.
What is not clear for me is how to specify/change how often solr must run.

From http://wiki.alfresco.com/wiki/Alfresco_And_SOLR i thought that the property was

alfresco.cron=0/15 * * * * ? *
How often to check if there is work to do

Although alfreco.cron sets the interval every 15 minutes, in my Alfresco installation I'm able typically to retrieve a node by metadata just after 20/30 seconds while in other installations the time to wait seems significantly longer. Could you explain what's the correct parameter or where this parameter is overridden?

Thanks,
Andrea

I think that cron expression is 15 seconds.

I am in the same boat as some one, where an uploaded document is not immediately available for search. I am using the SOLR subsystem as well. As i see from earlier answers, i should consider changing the subsystem from solr to lucene. Could anybody tell, how to change the subsystem from solr to lucene? are there any disadvantages by doing this? I am using Alfresco 4.0 version.

Is it true that indexing is less important in Alfresco 4.0 and it is advised to turn off this feature?

Please see the documentation for the search subsystem.
-> are there any disadvantages by doing this?
Performance is affected by having in transaction indexing, you can't index offline or share indexes between a cluster of servers.

-> Its not essential like it used to be but search is an important part of alfresco.

Rogers, thank you for your fast reply. If switching from solr to lucene, affects the performance as you said, i would not consider this approach.

coming back to the problem of not able to search the just saved document, what is the solution that you would suggest? There is a lag of about
4-5 seconds before i could search and retrive the document. can you point me to any documentation links that explains how to configure/overcome this issue?

thank you much in advance

Can you help me to find a javascript api to lookup for a new node from its noderef, something like search.findNode(..), but this API uses lucene index to work.

Thank you

Hi Forum,

Any updates in this problem??
In my case i am searching node as below
var nodes = search.luceneSearch("@type\\:customtype:\""+customproperty+"\"");

Problem :
when i upload document and try to view document using this query (from webscript )immediately it did not work <strong>sometimes</strong>.

Is it related to SOLR indexing?

What is the best way to solve this??

if i use

alfresco.cron=0/15 * * * * ? *  ‍

and change it to

alfresco.cron=0/2 * * * * ? *  ‍

that is 2 seconds to search for any work has any impact if i make this to 1 or 2 seconds???

As i mentioned it happens sometimes when i upload document after long time or after server restart is there any service which sleeps and it awake when i do some work on server???

Please guide me also suggest if any good approach i should follow to solve this

Version Alfresco 4.2e

DON'T use SEARCH for a document you just uploaded. That's bonkers!
