Pattern searching provides a means to widen a search beyond a single element. A pattern search can be executed using the command
:JavaSearch -p <pattern> [-t <type> -x <context> -s <scope> -i -a <action>]
When there is more than 1 result, those results will be placed into vim's quickfix list (:help quickfix) so that you can easily navigate them using vim's quickfix commands.
Vim command completion is supported through out the command with the excption of the pattern to search for.
:JavaSearch <Tab> :JavaSearch -p MyClass* <Tab> :JavaSearch -p MyClass* -t <Tab> :JavaSearch -p MyClass* -t all <Tab> :JavaSearch -p MyClass* -t all -x <Tab> :JavaSearch -p MyClass* -t all -x declarations
-p <pattern>: The pattern to search for.
-t <type> (Default: type): The type of element to search for where possible types include
-x <context> (Default: declarations): The context of the search, where possible context values include
-s <scope> (Default: all): The scope of the search where possible values include
-i: Ignore case when searching.
-a: The vim command to use to open the result (edit, split, vsplit, etc).
Eclim also provides a shortcut when issuing a pattern search for a type. You may simply invoke :JavaSearch supplying only the pattern.
To shorten things even more, there is support for camel case searching as well.
However, please note that camel case searching does not permit wild card characters ('*', '?').
Element searching allows you to place the cursor over just about any element in a source file (method call, class name, field) and perform a search for that element. Performing an element search is the same as performing a pattern search with the exception that you do not specify the -p option since the element under the cursor will be searched for instead.
If only one result is found and that result is in the current source file, the cursor will be moved to the element found.
As a convenience eclim also provides the command :JavaSearchContext. This
command accepts only the optional
-a argument described above, and will
perform the appropriate search depending on the context of the element under the
For those occasions that you find yourself browsing a third party source distribution that you want to be able to search without going through the steps of setting up a project, eclim provides an alternate searching mechanism. To utilize the alternate searching requires no change in behavior or commands, but to achieve the best results, you should know how it works.
The first thing worth noting is that the alternate search is currently a bit limited. It only supports searches involving types (classes, interfaces, annotations, and enums). It doesn't currently have any support for methods or fields.
Secondly, it can only search for and locate types within the current source tree. Searching across the jdk source or other third party source files without setting up an Eclipse or similar classpath, is difficult at worst, and slow at best.
With that said, I've found that when I'm walking through a third party source tree, my main focus is on finding referenced classes / interfaces quickly and easily, and the eclim alternate searching does just that.
Invoking the search is the same as the standard search mechanism. You simply use the same :JavaSearch command as you normally would. The only difference is that the alternate search doesn't support the -t option and will notify you of such if supplied.
When invoked, the alternate search will perform the following:
It will grab the full path of the current source file, strip off the package and search from the resulting directory.
Ex. When editing a file /usr/local/java/foo/src/org/foo/bar/Baz.java, the alternate search will first search the directory /usr/local/java/foo/src.
If no files are found in that directory, then it will proceed to search Vim's 'path' option (:h 'path' for more info on this option).
As an example, I have my 'path' set to '/usr/local/java/java-src' and in that directory is where I store all my third party source distributions (hibernate, spring, axis, etc.).
Once one or more files are found, the search will stop if the requested search was for declarations. For all searches, eclim will first try to find the declarations and if the user requested a search for implementors, references, or all, then the eclim will proceed to the next step.
For non-declaration searches, if multiple declaring source files are found, eclim will prompt you to narrow the results down to the type you would like results for.
Once eclim has narrowed the search down to the specific type to proceed with, it will then attempt to narrow the search down to a specific source distribution directory. To do this it locates the relevant entry from the 'path' option, tacks on one more level of the path from the resulting file, and commences its search from there.
Ex. When searching for all implementors of MyType, if eclim finds a file /usr/local/java/java-src/myproject/core/src/org/my/MyType.java and a 'path' entry of /usr/local/java/java-src exists, then eclim will deduce that that search must continue in the directory /usr/local/java/java-src/myproject.
This may seem a bit complicated for a simple search, but in practice it's actually quite simple, and as usual, I'm open to any and all comments and suggestions.
Alternate searching is bound to the performance of the file system and as such, the response time on Windows can be significantly slower than Linux. This is most noticable when searching for 'implementors', 'references', and 'all'. The number of and depth of the directories in your Vim 'path' option may also impact performance.

For example, if your projects follow maven hierarchy and you want the test references to be listed after the main code references, then you can configure this setting like so:
g:EclimJavaSearchSingleResult (Default: 'split') - Determines what action to take when a only a single result is found.
Possible values include:
This setting overrides the global default for all supported language types which can be set using the g:EclimDefaultFileOpenAction setting which accepts the same possible values.
