[jira] [Updated] (NUTCH-1140) index-more plugin, resetTitle method creates multiple values in the Title field

     [ https://issues.apache.org/jira/browse/NUTCH-1140?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

                0001-NUTCH-1140-2.x.patch

so this is still an issue, here is a sample list of urls in the wild that would trigger this problem:

http://www.10-s.com/site/tennis-supply/site-map.html
http://www.bigappleherp.com/site/content/big_apple_cares.html
http://www.bigappleherp.com/site/content/CareSheets.html
http://www.bigappleherp.com/site/content/company_information.html
http://www.bigappleherp.com/site/content/customer_service.html
http://www.bigappleherp.com/site/content/LiveAnimals.html
http://www.bigappleherp.com/site/content/testimonials_02.html
http://www.magellangps.com/lp/truckfamily/screens.html

Now base on a bit of a reading that I did on Content Disposition, it is a reasonable alternative way of determining a title which would mostly be just the file name, but it should NOT override the actual title if it exist as the information in the title are far more valueable than the file name. Not to mention that title is the actual title and should not be replaced if some other value exist.

> From the comments in MoreIndexingFilter.java, the index-more plugin is meant to reset the Title field of a document if it contains a Content-Disposition header. The current behavior is to add a Title regardless of whether one exists or not, which can cause issues down the line with the Solr Indexing process, and based on a thread in the nutch user list it appears that this is causing some users to mark the title as multi-valued in the schema:

> The following patch removes the title field before adding a new one, which has resolved the issue for me:
