Solr文件索引目录从数据库添加文件权限

Question

I'm using Solr to index a directory of pdf and word files. I want Solr to search these files but only return results based off a logged in user's permissions. Is it possible to index a directory of files as well as query a database containing the file permissions and add the data to the index as a xml entity and perform a filtered query on those results?

I am using WordPress as the CMS system with a file management plugin called Filebase. Filebase syncs with a directory to upload documents to the site. I have Solr configured to index the filebase directory containing the documents. Filebase has permissions that I set on each file.

My thought is if I can store the file's minimum user level position integer in the index I can then perform a filtered query to only display results with a user level of 'x'.

I hope this makes sense.

Yes, if you are on Solr 4+, you can push a Partial Update to Solr index.

SCHEMA

For partial update, all fields in your schema.xml need to be stored .

This is how your fields section should look like in schema.xml:

<fields>
  <field name="id" type="string" indexed="true" stored="true" required="true" />
  <field name="title" type="text_general" indexed="true" stored="true"/>
  <field name="description" type="text_general" indexed="true" stored="true" />
  <field name="body" type="text_general" indexed="true" stored="true"/>
  <field name="permission" type="integer" indexed="true" stored="true" />
</fields>

INDEXING:

You can first index all documents(directory of pdf and word) to your index.

Then you can send a partial update to the permission field for a particular id.

When you send partial update, what actually happens in background is:

• Solr will go and fetch values for all other fields for that document, such as title, description, body
• Delete old document
• Push new updated document to Solr index, with all existing fields as well as new permission field

Suppose you want to set permission=5 for document with id=document_1, your query should look like:

localhost:8080/solr/update?commit=true' -H 'Content-type:application/json' -d '[{"id":"document_1","permission":{"set":5}}]

Here is a good documentation on partial updates: http://solr.pl/en/2012/07/09/solr-4-0-partial-documents-update/
