Search first word in a field using filterrific

Question

I am using filterrfic gem to search an organization in the database. The problem I am facing is when I am searching for an organization whose name starts with National then I get the list of all the organizations which have National in their name. All I want is that it should just search the first word of the name_of_organisation field.

organisation.rb

def self.search(search)
    if search
        where('name_of_organisation LIKE ?', "%#{search}%")
    else
        all
    end
end


filterrific(
available_filters: [
        :search_query           
 ]
)

 scope :search_query, lambda { |query|
    return nil  if query.blank?

    terms = query.downcase.split(/\s+/)

    terms = terms.map { |e|
        (e.gsub('*', '%') + '%').gsub(/%+/, '%')
    }

    num_or_conds = 1
     where(
        terms.map { |term|
            "(LOWER(organisations.name_of_organisation) LIKE ?) 
        }.join(' AND '),
        *terms.map { |e| [e] * num_or_conds }.flatten
    )
}

Currently it displays all the Organisation as below: National Social Service Society for National Serivce

But What I want is that it should only search first word of the name_of_organisation field and display just Nation Social Service

Try changing this line:

where('name_of_organisation LIKE ?', "%#{search}%")

to:

where('name_of_organisation LIKE ?', "#{search}%")

Notice the removal of the first % in the search string. In this case, % represents any sequence of 0 or more characters . By removing the first one, it should only search for strings that start with your provided search string.
