content structure: content fragment jcr:content, jcr:content/data/master nodes have properties such as jcr:title, tags. see below.

need to get suggestions based on jcr:title , tags.

if jcr:title or tags array contains search term text return a suggestion.

 

 

what I tried:

tried with below new oak index only on jcr:title

<testSuggestIndex 
jcr:primaryType="oak:QueryIndexDefinition" 
async="[async]" 
compatVersion="{Long}2" 
evaluatePathRestrictions="{Boolean}true" 
includedPaths="[/content/dam/sample]" 
reindex="{Boolean}false" 
reindexCount="{Long}20" 
seed="{Long}6707975003957838906" 
type="lucene">
  <indexRules jcr:primaryType="nt:unstructured">
    <dam:Asset jcr:primaryType="nt:unstructured">
      <properties jcr:primaryType="nt:unstructured">
        <jcrTitle jcr:primaryType="nt:unstructured" boost="{Double}2.0"    name="jcr:content/jcr:title" nodeScopeIndex="{Boolean}true" propertyIndex="{Boolean}true" useInSpellcheck="{Boolean}true" useInSuggest="{Boolean}true"/>
      </properties>
    </dam:Asset>
  </indexRules>
<suggest jcr:primaryType="nt:unstructured" suggestUpdateFrequencyMinutes="{Long}1"/>
</testSuggestIndex>

 

1. contains query

2. rep:suggest query to get suggestions.

SELECT * FROM [dam:Asset] AS s WHERE ISDESCENDANTNODE([/content/dam/sample/faqs]) and CONTAINS(s.*, 'summit')

SELECT [rep:suggest()] FROM [dam:Asset] WHERE SUGGEST('summit') AND ISDESCENDANTNODE('/content/dam/sample/faqs')

 

both above queries return same results.

 

But once I added "tags" to oak index definition (see below) , rep:suggest query ,  contains query returning different number of results. in fact, tags property not seeming to be picked by rep:suggest query.

 

<testSuggestIndex 
jcr:primaryType="oak:QueryIndexDefinition" 
async="[async]" 
compatVersion="{Long}2" 
evaluatePathRestrictions="{Boolean}true" 
includedPaths="[/content/dam/sample]" 
reindex="{Boolean}false" 
type="lucene">
  <indexRules jcr:primaryType="nt:unstructured">
    <dam:Asset jcr:primaryType="nt:unstructured">
      <properties jcr:primaryType="nt:unstructured">
        
         <jcrTitle jcr:primaryType="nt:unstructured" analyzed="{Boolean}true" boost="{Double}2.0" name="jcr:content/jcr:title" nodeScopeIndex="{Boolean}true" propertyIndex="{Boolean}true" useInSpellcheck="{Boolean}true" useInSuggest="{Boolean}true"/>
        
         <modelTags jcr:primaryType="nt:unstructured" analyzed="{Boolean}true" boost="{Double}2.0" name="jcr:content/data/master/tags" nodeScopeIndex="{Boolean}true" propertyIndex="{Boolean}true" useInSpellcheck="{Boolean}true" useInSuggest="{Boolean}true"/>

      </properties>
    </dam:Asset>
  </indexRules>
<suggest jcr:primaryType="nt:unstructured" suggestUpdateFrequencyMinutes="{Long}1"/>
</testSuggestIndex>

 

 at this time, I do not know what is wrong with my oak index definition. I need suggest on multiple properties one property is jcr:title is at jcr:content node level, another property tags is at jcr:content/data/master level as shown in screenshots.

 

any help is appreciated, I looked at several blogs and tried this but suggest not seeming to pick tags property on all nodes.

 

note: every time I changed index definition, reindex done as well.

 

Thanks,

Sri

@sreenu539 , make sure you have "path": "jcr:content/data/master" included in your index definition as shown below

@shubhanshu_singh I added aggregates for "jcr:content", "jcr:content/data/master" no change in number of results for query rep:suggest.

Can you share your query execution plan here?

seems like "includedPaths" , "ISDESCENDANTNODE" not working fine. why?

 

 

 

 

<testSuggestIndex jcr:primaryType="oak:QueryIndexDefinition" async="[async]" compatVersion="{Long}2" evaluatePathRestrictions="{Boolean}true" includedPaths="[/content/dam/sample]" reindex="{Boolean}false" type="lucene">
<aggregates jcr:primaryType="nt:unstructured">
  <dam:Asset jcr:primaryType="nt:unstructured">
    <include0 jcr:primaryType="nt:unstructured" path="jcr:content"/>
    <include8 jcr:primaryType="nt:unstructured" path="jcr:content/data/master"/>
  </dam:Asset>
</aggregates>
<indexRules jcr:primaryType="nt:unstructured">
  <dam:Asset jcr:primaryType="nt:unstructured">
    <properties jcr:primaryType="nt:unstructured">
      <jcrTitle jcr:primaryType="nt:unstructured" analyzed="{Boolean}true" boost="{Double}2.0" name="jcr:content/jcr:title" nodeScopeIndex="{Boolean}true" propertyIndex="{Boolean}true" useInSpellcheck="{Boolean}true" useInSuggest="{Boolean}true"/>

       <modelTags jcr:primaryType="nt:unstructured" analyzed="{Boolean}true" boost="{Double}2.0" name="jcr:content/data/master/tags" nodeScopeIndex="{Boolean}true" propertyIndex="{Boolean}true" useInSpellcheck="{Boolean}true" useInSuggest="{Boolean}true"/>

    </properties>
  </dam:Asset>
</indexRules>
<suggest jcr:primaryType="nt:unstructured" suggestUpdateFrequencyMinutes="{Long}1"/>
</testSuggestIndex>

 

 

 

 

 

 

above is modified testSuggestIndex at /oak:index node. Aggregators added for jcr:content, jcr:content/data/master

 

for word 'summit' returns some results

rep:suggest

for rmd there is some content tagged with tag sample:rmd

rmd-cf.png

 

no results for rep:suggest

As you can see above the query seems to be returning the results correctly after adding "jcr:content/data/master" in aggregates. 
For more info you can refer documentation : Jackrabbit Oak – Lucene Index (apache.org)

@shubhanshu_singh For word "rmd" in my case, not returning any results.

It only returning results if I take out ISDESCENDANTNODE or includedPaths. 

 

Other than that, I see index you created is same as what I created.

@sreenu539, the reason why your query with "rmd" is not returning any result is because - the subset is done by filtering the top 10 suggestions. So, it's possible to get no suggestions for a subtree query, if top 10 suggestions are not part of that subtree. For details look at OAK-3994 and related issues. It is mentioned in the Jackrabbit Oak documentation as a note.

@shubhanshu_singh  sub tree mentioned in ISDESCENDANTNODE has tags, words which say "rmd" , It seems "includedPaths" is not supported, at the least for suggest.

@sreenu539 The subtree might have the results but check this. 

From the query execution plan you can see - the suggest query first tries to get all the relevant suggestion - it takes the top 10 result and then apply your subtree filtering 

Now if the results under '/content/dam/sample/faqs' does not fall into the top 10 results you may get zero results.
