Advanced search option in Solr matching DtSearch parameters

We are replacing the search and indexing module in the DtSearch application with Solr, using solrnet as the Solr .net library.

We are relatively new to Solr / Lucene and need some help / direction to understand the more advanced search options in Solr.

The current application supports the following search options using DtSearch:

1) Word (s) or phrase

2) Exact words or phrases

3) Not these words or phrases

4) One or more words ("A" OR "B" OR "C")

5) Closeness of a word with n words of another word

6) Numeric range - From - to

7) Option

... Stemming (search * find search or search)

... Synonym (search and search search or look)

... Fuzzy within n letters (p% arts finds paris)

... Background homonyms (# Smith also finds Smith and Smythe)

As an example, a search query that is generated to be posted to DtSearch for the following use:

  • Search phrase: general collection

  • Exact phrase: linq

  • Not these words: sql

  • One or more of these words: ICollection or ArrayList or Hashtable

  • Proximity: csharp within 4 words of the language

  • Parameters:

    and. Morphological

    b. Synonym

    from. Fuzzy within 2 letters

    e. Background homonyms

    Search query: generic * collection * generic & Collection & # generic # collection g %% eneric c %% ollection "linq" -sql ICollection OR ArrayList OR Hashtable csharp w / 4 language

We were able to do simple searches (search by terminology in the content file) with highlighting using Solr. Now we need to replace these Solr / Lucene parameters.

Can anyone provide some guidance on what / where we should look.
