Re: [SolrNet] How can i boost a field dynamically at index time using solrnet

[Mauricio Scheffer]

Here are the options I can think of:

1. Index using a Dictionary<string,object> document type as described in https://groups.google.com/d/topic/solrnet/iZlaw7Yn4_U/discussion

2. Resolve IReadOnlyMappingManager from the IoC container. Locate the field you want to boost using GetFields(). Mutate the SolrFieldModel's Boost property as needed for each document you add. This would preclude the parallelization of the indexing process.

3. Replace the default ISolrDocumentSerializer<T> with your own (using the default one as reference for your implementation).

1. and 2. are quite hackish. 3. is the cleanest solution, but may require a bit more code.

Cheers

Hi,

Currently for index time field boosting i am using mapping attribute and giving a static boost like below.

    [SolrUniqueKey("StudentID")]

     public int JobseekerID { get; set; }

    [SolrField("FName")]

     public string FName { get; set; }

    [SolrField("LName")]

     public string LName { get; set; }

    [SolrField("Subject"),Boost=50]

     public string Subject { get; set; }

    [SolrField("SubjectRating")]

     public string SubjectRating { get; set; }

Is there a way i can give the boost dynamically ?

For example I will calculate the boost according to SubjectRating and apply that value to boost the subject field ?

Or using reflection i have to change the attribute value ?

Please guide me.

Thanks in advance.

I have already followed the second approach and achieved what i wanted but will definitely give a try to third approach.

Thanks
