Solr vs ElasticSearch

I've been hearing more and more about ElasticSearch. Can anyone give me 
a rough overview on how these two technologies differ. What are the 
strengths/weaknesses of each. Why would one choose one of the other?

Thanks

Re: Solr vs ElasticSearch

Mark,

Nice email address.  I personally have no idea, maybe ask Shay Banon
to post an answer?  I think it's possible to make Solr more elastic,
eg, it's currently difficult to make it move cores between servers
without a lot of manual labor.

RE: DIH: Exception with "Too many connections"

Stephan,

Your advice (check the process list) gave me an important clue for my
solution.
I changed my database connection to the slave instead of master, so that I
can use more threads.
Thank you very much!

*** 

François,

My setting is the default value:
max_connections = 151  
max_user_connections = 0 

I will think of changing the max_connections when I increase the number of
cores.
Thanks!

***

Fuad,

So far, I can handle DIH with my setting.
Thanks for letting me know!

Regards,
Tiffany

RE: Solr vs ElasticSearch

Interesting wordings:
"we want real-time search, we want simple multi-tenancy, and we want a
solution that is built for the cloud"

And later,
" built on top of Lucene."

Is that possible? :)
(what does that mean "real time search" anyway... and what is "cloud"?)

community is growing!

P.S.
I never used Elastic Search, but I used Compass before moving to SOLR. And
Compass uses wordings like as "real-time *transactional* search". Yes, it's
good and it has own use case (small databases, reduced development time,
junior-level staff, single-JVM environment)

I'd consider requirements at first, then will see which tool simplifies my
task (fulfils most requirements). It could be Elastic, or SOLR, or Compass,
or direct Lucene, or even SQL, SequenceFile, SQL, in-memory TreeSet, and
etc. Also depends on requirements, budget, team&skills.

Re: collapse component with pivot faceting

Hi,
           Actually  currently I am using solr version 3.0 . I applied 
the field collapsing patch of solr . The field collapsing work fine with 
collapse.facet=after for any facet.field but when I  try to use  
facet.pivot query after collapse.facet=after it does nt show any 
results. Also pivot faceting feature is not present in solr 3.0.
So which pivot faceting patch should I use with solr 3.0,solr 4.0 
support the pivot faceting but it does not have field collapsing 
feature.Can anyone guide me regarding which Solr version support both 
field collapsing and pivot faceting .

Thanks in Advance!

Index vs. Query Time Aware Filters

We have very long schema files for each of our language dependent query
shards.  One thing that is doubling the configuration length of our main
text processing field definition is that we have to repeat the exact same
filter chain for query time version EXCEPT with a queryMode=true parameter.

Is there a way for a filter to figure out if it's the index vs. query time
version?

A similar wish would be for the filter to be able to figure out the name of
the field currently being indexed.  This would allow a filter to set a
parameter at runtime based on fieldname, instead of boilerplate copying the
same filterchain definition in schema.xml EXCEPT for one parameter.  The
motivation is again to reduce errors and increase readability of the schema
file.

Re: Solr vs ElasticSearch

Nice article... 2 ms better than 20 ms, but in another chart 50 seconds are not as good as 3 seconds... Sorry
for my vision...

SOLR pushed into Lucene Core huge amount of performance improvements...

Anyway to know changed documents?

Hi everyone,
   If I have two server ,their indexes should be synchronized. I changed A's index via HTTP send document
objects, Is there any config or some plug-ins to let solr know which objects are changed and can push it B ?
  Any suggestion will be appreciate.
  Thanks :)
