Re: Best strategy for logging & security

[Vishal Swaroop]

I am using log4j.properties which logs core name with each query...

Is there a way to generate separate logs for each core ?

Thanks Rajesh... just trying to figure out if *logstash *is opensource and
free ?

Best strategy for logging & security

[Vishal Swaroop]

It will be great if you can provide your valuable inputs on strategy for
logging & security...


Thanks a lot in advance...



Logging :

- Is there a way to implement logging for each cores separately.

- What will be the best strategy to log every query details (like source
IP, search query, etc.) at some point we will need monthly reports for
analysis.



Securing SOLR :

- We need to implement SOLR security from client as well as server side...
requests will be performed via web app as well as other server side apps
e.g. curl...

Please suggest about the best approach we can follow... link to any
documentation will also help.



Environment : SOLR 4.7 configured on Tomcat 7  (Linux)

Re: distributed search limitations via SolrCloud

[Vishal Swaroop]

Thanks a lot Erick... great inputs...

Currently our deployment is on Tomcat 7 and I think SOLR 5.x does not
support Tomcat but runs on its own Jetty server, right ?
I will discuss this with the team.

Thanks again.

Re: distributed search limitations via SolrCloud

[Vishal Swaroop]

Thanks a lot Erick... You are right we should not delay moving to
sharding/SolrCloud process.

As you all are expert... currently we are using SOLR 4.7.. Do you suggest
we should move to latest SOLR release 5.1.0 ? or we can manage the above
issue using SOLR 4.7

distributed search limitations via SolrCloud

[Vishal Swaroop]

Currently, we have SOLR configured on single linux server (24 GB physical
memory) with multiple cores.
We are using SOLR joins (https://wiki.apache.org/solr/Join) across cores on
this single server.

But, as data will grow to ~2 billion we need to assess whether we’ll need
to run SolrCloud as "In a DistributedSearch environment, you can not Join
across cores on multiple nodes"

Please suggest at what point or index size should we start considering to
run SolrCloud ?

Thank you all... You all are experts...

I will go with double as this seems to be more feasible.

Re: Suggestion on field type

[Vishal Swaroop]

Thanks Erick... I can ignore the trailing zeros

I am indexing data from Vertica database... Though *double *is very close
but it SOLR indexes 14 digits after decimal
e.g. actual db value is 15 digits after decimal i.e. 249.81735425382405*2*
SOLR indexes 14 digits after decimal i.e. 249.81735425382405

As these values will be used for big data analysis, so I am wondering if it
might impact the result.


Any suggestions ?

Regards

Re: Suggestion on field type

[Vishal Swaroop]

Thank you John and Jack...

Looks like double is much closer... it removes trailing zeros...
a) Is there a way to keep trailing zeros
double : 194.846189733028000 indexes to 194.846189733028


b) If I use "String" then will there be issue doing range query

float

277.677836785372000 indexes to 277.67783

Suggestion on field type

[Vishal Swaroop]

Please suggest which numeric field type to use so that I can get complete
value.

e.g value in database is : 194.846189733028000

If I index it as float SOLR indexes it as 194.84619 where as I need
complete value i.e 194.846189733028000
I will also be doing range query on this field.

Help to index nested document

[Vishal Swaroop]

Need your valuable inputs...

I am indexing data from database (one table) which is in this example
format :
id name value
1 Joe 102724904
2 Joe 100996643

- id is primary/ unique key
- there can be same "name" but different "value"
- If I try "name" as unique key then SOLR removes duplicate and indexes 1
document

- I am getting the result in this format... Is there as way I can index
data in a way so that I can "value" can be child for "name"...
"response": {
"numFound": 2,
"start": 0,
"docs": [
  {
"id": "1",
"name": "Joe",
"value": [
  "102724904"
]
  },
  {
"id": "2",
"name": "Joe",
"value": [
  "100996643"
]
  }...

Expected format :
"docs": [
  {
"name": "Joe",
"value": [
  "102724904",
  "100996643"
]
  }

How to get exact match along with text edge_ngram

[Vishal Swaroop]

We have item_name indexed as text edge_ngram which returns like results...

Please suggest what will be the best approach (like "string" index (in
addition to "...edge_ngram"... or using copyField...) to search ALSO for
exact matches?

e.g. url should return item_name as "abc" entries only... I tried item_name
in quotes ("abc") but no luck...
http://localhost:8081/solr/item/select?q=item_name:abc&wt=json&indent=true
But, I get abc-1, abc-2... as result, however I only need "abc" entries.

Thanks Kaushik & Erick..

Though I can populate uuid by using combination of fields but need to
change the type to "string" else it throws "Invalid UUID String"


a) I will have ~80 millions records and wondering if performance might be
issue
b) So, during update I can still use combination of fields i.e. uuid ?

Re: Suggestion on indexing complex xml

[Vishal Swaroop]

Thanks for your time and suggestions Alex...

a) So, if I use xslt... then SOLR output result will be xml, or there is a
trick to get json also

b) I am trying to figure out xslt template for my xml (as below) input to
differentiate "parameter1" & "parameter2" as some elements are common (e.g.
name, value)... any help will be great.
Trying to figure out best approach for below xml.

c) Is there a way to get the attribute (e.g. version) also for element

Suggestion on indexing complex xml

[Vishal Swaroop]

Hi,

I am able to index XML with same "name" element but in different XPATH by
using XPathEntityProcessor "forEach" (e.g. below)

Just wondering if there is better way to handle this xml format.

a) Is there any better way to handle this scenario as xml file will have
multiple sub-menu attributes (e.g. A, B, C, D...)
and I will have to specify each in "forEach" attribute.

b) How to differentiate xml result from two entities defined in
data-config.xml

Example xml


Waffles
$2.95


Strawberry

Light waffles covered with strawberries

$3.95



Example dataConfig















Result :
"docs": [
  {
"name": "Waffles",
"value": "$2.95"
  },
  {
"description": "Light waffles covered with strawberries",
"name": "Strawberry",
"value": "$3.95"
  }
]

Add fields without manually editing Schema.xml.

[Vishal Swaroop]

Hi,

Just wondering if there is a way to handle this use-case in SOLR without
manually editing Schema.xml.

Scenario :
We have xml data with some elements/ attributes which we plan to index.
As we move forward there can be addition of xml elements.

Is there a way to handle this with out manually adding fields /changing in
schema.xml ?

Thanks

Suggestion on distinct/ group by for a field ?

[Vishal Swaroop]

Please suggest on how to get the distinct count for a field (name).

Summary : I have data indexed in the following format
category name value
Cat1 A 1
Cat1 A 2
Cat1 B 3
Cat1 B 4

I tried getting the distinct "name" count... but it returns 4 records
instaed of 2 (i.e. A, B)
http://localhost:8081/solr/core_test/select?q=category:Cat1&fl=category,name&wt=json&indent=true&facet.mincount=1&facet=true

In Oracle I can easily perform the distinct count using groop-by
select c.cat, count(*distinct *i.name) from category c, itemname i, value v
where v.item_id = i.id and i.cat_id = c.id and c.cat ='Cat1' *group by
c.cat *
Result:
"Cat1" "2"

Thanks

Ignore whitesapce, underscore using KeywordTokenizer... EdgeNGramFilter

[Vishal Swaroop]

I am trying to implement type-ahead suggestion for single field which
should ignore whitesapce, underscore or special characters in autosuggest.

It works as suggested by Alex using KeywordTokenizerFactory but how to
ignore whitesapce, underscore...

Example itemName data can be :
"ABC E12" : if user types "ABCE" suggestion should be "ABC E12"
"ABCE_12" : if user types "ABCE1" suggestion should be "ABCE_12"

It looks like it works as expected... I removed "EdgeNGramFilterFactory"

is final version..


   



   
   

   


So... when is right to use <*tokenizer *

b) I am looking to display the result as type-ahead suggestion which might

Output expected "A", "AB", "ABC", "ABC1"... so on
Data can also have underscores, dashes

How to make edge_ngram work with number, underscores, dashes and space

[Vishal Swaroop]

Hi,

May be this is basic but I am trying to understand which Tokenizer and
Filter to use. I followed some examples as mentioned in solr wiki but
type-ahead does not show expected suggestions.

Example itemName data can be :
- "ABC12DE" : It does not work as soon as I type 1.. i.e. ABC1
- "ABC_12DE", "ABC 12DE"
- Data can also have underscores, dashes
- I am tyring ignorecase auto suggest

Is defining facet fields in solrconfig.xml mandatory ?

[Vishal Swaroop]

Hi,

I am exploring faceting in SOLR in collection1 example Faceting fields are
defined in solrconfig.xml under browse request handler which is used in
in-built "VelocityResponseWriter"

...
   on
   cat


I think it is not at all mandatory to define facet fields in
solrconfig.xml, right ?
Instead we can directly use facet in query URLs... e.g.
http://
:8081/solr/mytestcollection/select?q=*:*&rows=0&facet=true&facet.field=item_id&facet.field=item_type&wt=json&indent=true

Just wondering if there are open source framework to query and
