[ANN] Searchable Plugin 0.4 ships

[Maurice Nicholson-2]

Searchable Plugin 0.4 is finally here!

I guess most of you have been using the 0.4-SNAPSHOT for a while, so here's what's happened recently:

* Upgraded to Compass 1.2.1 which includes Lucene 2.2
* Highlighting: http://grails.org/Searchable+Plugin+-+Searching#SearchablePlugin-Searching-Highlighting
* Term Frequencies: http://grails.org/Searchable+Plugin+-+Searching#SearchablePlugin-Searching-termFreqs
* The start of a mapping DSL: http://grails.org/Searchable+Plugin+-+Mapping#SearchablePlugin-Mapping-MappingDSL
* Better default mapping of embedded domain classes: http://grails.org/Searchable+Plugin+-+Mapping#SearchablePlugin-Mapping-Defaultmappingrules

Cheers,
Maurice

*Darryl bows before the master*

Thanks Maurice, the Searchable plugin is, I think, the most powerful and impressive of all the Grails plugins and these improvements only serve to entrench that fact.

Regards,
Darryl

Computed constants.
Hi Maurice, congratulations for the final release!
I still had lots of errors from the SVN version of a couple of days ago,
but I'm gonna try this one.
I was reading the updated documentation and I found the section about
constants.
I understand that you can index "custom" mappings to a domain instance,
that's very useful.
What I was wondering is whether those constant mappings could be
computed. That is, computed out of other properties (for example a
concatenation of two properties, or maybe a substring of one of them
plus the temperature in Madagascar at that time... some crazy example :-))
Maybe it could accept a clousre, like:
    constant  name: "myComputed" ,   value: {
"bla"+tempMadagascar+(someProp*3) }

I guess those constants are indexed when the object is saved/updated, so
all the values are already there.

if you do get errors with the latest version please shout :-)

yeah this is on the roadmap (in my head); the closure would be given an instance of the domain class so you could refer to the instance with it, eg,

    name: "bugId", value: { -> "${it.project.shortName}-${it.number}" }

Compass has the concept of "dynamic-meta-data" for this but with that you basically define the expression as a string, which can get cumbersome for large expressions, because when configuring the mapping with native compass you're either in XML-land or annotation -land, neither of which are actually code :-)

Regarding that trying to marshall null id bug you found, I could reproduce it easily with a Grails app, but then when I tried reproducing it in a paired down Java+Hibernate+Compass Test case, well of course I got a different problem! I think there are many more moving parts in the Grails app that I'm not yet aware of, so I need to do more investigation, but it's now the top priority for me.

Thanks mate, glad you like it!

But I reckon it depends on the app you're writing as to which one(s) you find the most useful :-)

Well. same problems with the new version :-(
Clean project, Grails 1.0.1
Two domain objects in a bi-directional one-to-many, very simple and
classic example.

class User {
  static searchable =  true
  String name
  static hasMany = [albums:Album]
}

class Album {
  static searchable = true
  String title

  User   owner
  static belongsTo= User
}
------

The following code fails when saving the user:

     def u1= new User(name:'barcho king')

     def a1= new Album(title:'el album del pasto en el universo')
     def a2= new Album(title:'bart the king nenene')

     u1.addToAlbums(a1).addToAlbums(a2)
     u1.save()    // FAILS HERE!

The User is actually inserted into the database:
  -->   insert into user (version, name) values (0, 'barcho king')

But I think the error happens when cascading down to the albums:
(example trace from within a grails controller/action, but the same
problem happens from the grails console and the BootStrap)

I've tried to change the User's mapping to:
 static searchable =  {
      albums(component: true)
  }

But then it gives lots of errors when grails starts:

[10266] context.ContextLoader Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating
bean with name 'compassGps': Cannot resolve reference to bean 'compass'
while setting bean property 'compass'; nested
exception is org.springframework.beans.factory.BeanCreationException:
Error creating bean with name 'compass': FactoryBean threw exception on
object creation; nested exception is java.lang.NullPointerException

and lots similar to the above.  This *used* to work in the old
(mid-2007) 0.4 snapshot, althouth there was some weird stuff with the
termFreqs, giving higher results than it should. Probably some
double-counting due to the component option.

I've also tried several other options for mappings, with no luck. I even
started to try annotation mapping but it gets too involved and complicated.

Now, I really do wonder how are other people using this plugin if I
can't make it work even for the simplest of examples (taken from the web
page).
I'd really like to use this plugin  :-)

I am experiencing the same problem :-(

I am trying to search multiple domain classes, but this prevents me from creating them. Does anyone have a solution for this problem?

Cheers,
Jeroen

Well. same problems with the new version :-(
Clean project, Grails 1.0.1
Two domain objects in a bi-directional one-to-many, very simple and
classic example.

class User {
  static searchable =  true
  String name
  static hasMany = [albums:Album]
}

class Album {
  static searchable = true
  String title

  User   owner
  static belongsTo= User
}
------

The following code fails when saving the user:

     def u1= new User(name:'barcho king')

     def a1= new Album(title:'el album del pasto en el universo')
     def a2= new Album(title:'bart the king nenene')

     u1.addToAlbums(a1).addToAlbums(a2)
     u1.save()    // FAILS HERE!

The User is actually inserted into the database:
  -->   insert into user (version, name) values (0, 'barcho king')

But I think the error happens when cascading down to the albums:
(example trace from within a grails controller/action, but the same
problem happens from the grails console and the BootStrap)

I've tried to change the User's mapping to:
 static searchable =  {
      albums(component: true)
  }

But then it gives lots of errors when grails starts:

[10266] context.ContextLoader Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating
bean with name 'compassGps': Cannot resolve reference to bean 'compass'
while setting bean property 'compass'; nested
exception is org.springframework.beans.factory.BeanCreationException:
Error creating bean with name 'compass': FactoryBean threw exception on
object creation; nested exception is java.lang.NullPointerException

and lots similar to the above.  This *used* to work in the old
(mid-2007) 0.4 snapshot, althouth there was some weird stuff with the
termFreqs, giving higher results than it should. Probably some
double-counting due to the component option.

I've also tried several other options for mappings, with no luck. I even
started to try annotation mapping but it gets too involved and complicated.

Now, I really do wonder how are other people using this plugin if I
can't make it work even for the simplest of examples (taken from the web
page).
I'd really like to use this plugin  :-)
