eea.similarity 1.0

Introduction

EEA Similarity provides cosine-based suggestions to a search string. Initial use is to provide a list of possible duplicates when adding content (based on the entered title)

Installation

zc.buildout

If you are using zc.buildout and the plone.recipe.zope2instance recipe to manage your project, you can do this:

• Update your buildout.cfg file:

  • Add eea.similarity to the list of eggs to install

  • Tell the plone.recipe.zope2instance recipe to install a ZCML slug

  [instance]
  ...
  eggs =
    ...
    eea.similarity
  
  zcml =
    ...
    eea.similarity

• Re-run buildout, e.g. with:

  $ ./bin/buildout

You can skip the ZCML slug if you are going to explicitly include the package from another package’s configure.zcml file.
