First sorry for the post to here and the solr list, not sure where this is
most appropriately asked but since there is no response there I figured I'd
try here...
I have what I believe to be a fairly unique use case (as i have not seen it
mentioned before) that I'm looking for some thoughts on. I
Dear Team,
I am trying to build a search engine for fetching person info based on name
or email Id. For this I have standard Analyzer & wildcard. If I enter case
senstive query I get the result. but how to go about for case in-senstive
I mean if I search for rohan or Rohan should be same, Curren
Add LowercaseFilterFactory to your analysis chain for the fieldType
both at query and index time. You'll need to re-index.
The admin UI/analysis page will help you understand the effects
of each analysis step defined in your fieldTypes.
Best,

I was assuming this was a Lucene question...
The StandardAnalyzer already includes the lower case filter, so the default
should be case-insensitive query.
See:

If the question was real
Hi,
Wildcard queries don't use the Analyzer, so they are case sensitive. Most of
Lucene's query parsers allow to lowercase although there is a wildcard, but xou
have to enable this.
In most cases it is recommended to use a plain simple analyzer for fields using
wildcards. If you also have ste
Hi,
I am new with Lucene Analyzer. I would like to get the full English tokens
from SmartChineseAnalyzer. But I’m only getting stems. The following code
has predefined the sentence in "testStr":
String testStr = "女单方面，王适娴second seed和头号种子卫冕冠军西班牙选手马
林first seed同处1/4区，3号种子李雪芮和韩国选手Korean player成池铉处在
The easiest thing to do is to create your own analyzer, cut and paste the
code from org.apache.lucene.analysis.cn.smart.SmartChineseAnalyzer into it,
and get rid of the line in createComponents(String fieldName, Reader
reader) that says
result = new PorterStemFilter(result);

Thanks Michael. That works well. Not sure why SmartChineseAnalyzer is
final, otherwise we could overwrite createComponents().
New output:
女 单 方面 王 适 娴 second seed 和 头号 种子 卫冕 冠军 西班牙 选手 马 林
first seed 同 处 1 4 区 3 号
种子 李 雪 芮 和 韩国 选手 korean player 成 池 铉 处在 2 4 区 不过 成 池 铉

Hi,
it's much easier to create own analyzers since Lucene 5.0 (without defining
your own classes):
https://lucene.apache.org/core/5_2_1/analyzers-common/org/apache/lucene/analysis/custom/CustomAnalyzer.html
Using the builder you can create your own analyzer just with a few lines of
code. The nam
Thanks Uwe. This seems to be a handy tool. My problem is I need a better
example (tutorial maybe) to show me what are necessary/default filters a
SmartChineseAnalyzer or JapaneseAnalyzer needs. In this case, I guess I
need a HMMChineseTokenzier and a stop filter but not a porter stem filter.
