Hi Ivo, first of all I would like to appreciate for this great extension and your work. I have read through following topics .

it seems , it is really needed for a web search.

In installlation instruction 4 and five , it is bit hard to follow ( sorry it is my problem am not an expert , its takes time to understand things ). I am trying to get more information about it from following links.

Hi Ivo, I have read the your documentation about ngsuggest.

I understood the background working of this extension.

But can u plz help me understand these things. I couldn't catch it , Any help will be appreciable. I have no other way to get more info about it

Following actions are applied when indexing happens (similar as when querying):

  1. text is tokenized by white space
  2. stop filter factory removes unwanted words defined in 'stopwords.txt' /*what is its purpose*/
  3. factory for slicing and combining words is called (useful for slicing words with numbers) but without concatenations /* what it is*/
  4. lower case factory does casing normalization

Next, new field 'ngsuggest_text' is added under <fields> node:

<field name="ngsuggest_text" 
       type="text4suggest" 
       indexed="true" 
       stored="true" 
       multiValued="true" 
       termVectors="true" />

Finally, new field should be filled with content under <schema> node:

<copyField source="attr_*" dest="ngsuggest_text" />
<copyField source="meta_name_s" dest="ngsuggest_text" />
<copyField source="meta_url_alias_s" dest="ngsuggest_text" />
