add query restriction option to open street map provider

[smeijer]

Are the already supported (and native Nominatim) parameters insufficient?

https://wiki.openstreetmap.org/wiki/Nominatim#Parameters

countrycodes=[,][,]...

Limit search results to a specific country (or a list of countries).

should be the ISO 3166-1alpha2 code, e.g. gb for the United Kingdom, de for Germany, etc. **viewbox**=,,, The preferred area to find search results. Any two corner points of the box are accepted in any order as long as they span a real box.

// import
import { OpenStreetMapProvider } from 'leaflet-geosearch';

// setup
const provider = new OpenStreetMapProvider({
  params: {  
    viewbox: '...',
    countrycode: 'nl',
  }
});

// search
const results = await provider.search({ query: input.value });

Even if that would be insufficient, wouldn't it be enough to wrap the search command?

// search
const results = await provider.search({ query: input.value + ' your modifier' });

i tried to add use the parameter but it didn't restrict the user query. after search i found out that parameter and query doesn't work together you can only use one of them.

// search
const results = await provider.search({ query: input.value + ' your modifier' });

this will do it but i have to re redo all the customization you did the search-box.

i think it will a good feature to add restriction on the user query with out having to re-do the customization.

My apologies for the long wait. I'm going to close this one, and will think of a solution on the higher level so that all providers can use some query manipulation before the request is being send. That solution will be tracked in #215.

At the same time, I've updated the docs to provide more information about how to limit results by using the providers' optional parameters.

Again, thanks for taking the trouble of opening a PR, and my apologies for the long wait.
