Hi Francesco,



do you have other indexes within your Oak repo ?

No. We haven’t other indexes.

It might be that the query engine selects a different index which only acts on 
[nt:file] nodes.

You can try checking the plan [1] for your query and compare with the [nt:base] 
version.

It might also be useful to enable debug logging for 
org.apache.jackrabbit.oak.query, that will allow you to check the costs 
associated to each index so that it should be easier to eventually tweak the 
index definitions accordingly (note that the query engine selects the index 
with the lowest cost), e.g. you should see something like:

...

cost for solr is 1.4

cost for lucene is 1.2

cost for reference is Infinity

...

We have already activated debug in oak and we noticed that when we use a query 
with the inner join then cost for solr is Infinity and query is not sent to solr



Do you Know if inner join is supported by Oak to use Solr ?



Regards,

Tommaso

R: problem on oak jcr sql2 query

2017-03-28 Thread Ancona Francesco 
We have wrapped oak jcr implementation with our data model, so it's not so easy 
give you our unit test (our sw is not yet open sourece :-)) 
Besides we know the documenti is correctly indexed, cause we see it in solr; so 
you can use any type of pdf: oak manage full text correctly. 

Anyway we tried to use a query like this to optimize performance: 
SELECT parent.* FROM [nt:file] AS parent INNER JOIN [nt:resource] AS child ON 
ISCHILDNODE(child,parent) WHERE CONTAINS(child.*, ' company') or 
CONTAINS(parent.*, ' company')
  
But we saw that index planner doesn't permit solr query (oak doesn't use solr 
for the query). So we can't find words inside content (nt:resource)

What is wrong ?
Why oak doesn't use solr for full text query ?
 
Thanks in advance,
best regards

In another document ([nt:file] that doesn't have childs) i'd want match only

Actually  i resolved the problem executing a query like this: select p.* from

this can work but it's surely worse in terms of performance as you retrieve and 
skip some docs you don't really need.
If you can provide the PDF via a link or, better, a unit test we can probably 
help you more effectively.

Tommaso

R: problem on oak jcr sql2 query

2017-03-27 Thread Ancona Francesco 
Sorry.

We are using Oak 1.4.10 and solr 4.10.4

i send you also a pdf example: the searched word is "sezione"

In another document ([nt:file] that doesn't have childs) i'd want match only 
through metadata that contains the word "company"

Actually  i resolved the problem executing a query like this: select p.* from 
[nt:base] as p where .. contains (p.*, "company") or contains (p.*, 
"sezione")

Then i explore (programmatically and after the query response) jcr nodes to set 
only nodes that are [nt:file]

Is it the correct approach ?

Thanks in advance,
best regards
