Solr完全导入有问题

Question

I am running Sol 3.6 version with 5 cores.I do full import whenever my application starts up. I am simply calling http://:/solr//dataimport?command=full-import

As of now i am facing 2 weird issues.

1. One of the core's data is empty(index got deleted).Dont know why.
2. In my query i had put restriction to load only 6 months old data.Sometimes i get data which is much older than 6 months.

Questions : What does default "clean=true" mean?In my case it is true.Does that mean i will not see data once i execute following query? http://:/solr//select/?q= %3A &version=2.2&start=0&rows=10&indent=on

Answer 1

I experienced the same problem.

Executing full-import with clean=false means the DIH will erase all the documents from the index before importing. After the process is completely done, DIH will execute a commit, making the changes visible.

What happened to me is the following:

1. Execute full-import with a DB query that takes really long

2. Delete documents by query, with commitWithIn set.

3. Index is empty.

Besides that, this problem did not happen with autocommit configured as follow:

<autoCommit>
   <maxTime>1000</maxTime>
   <openSearcher>false</openSearcher>
 </autoCommit>

but did happen with

<autoCommit>
  <maxTime>1000</maxTime>
  <openSearcher>true</openSearcher>
</autoCommit>

and with autoSoftCommit

<autoSoftCommit>
  <maxTime>1000</maxTime>
</autoSoftCommit>
