Search endpoints vary in case sensitivity and substring/fullstring requirements

[mileswwatkins]

It'd be nice if these were standard across all search endpoints. Here're some examples:

Divisions:

• Doesn't work: http://api.opencivicdata.org/divisions/?name=United
• Doesn't work: http://api.opencivicdata.org/divisions/?name=united%20states
• Works: http://api.opencivicdata.org/divisions/?name=United%20States

Jurisdictions:

• Works: http://api.opencivicdata.org/jurisdictions/?name=Rhode
• Works: http://api.opencivicdata.org/jurisdictions/?name=rhode%20island
• Works: http://api.opencivicdata.org/jurisdictions/?name=Rhode%20Island

Organizations:

• Doesn't work: http://api.opencivicdata.org/organizations/?name=Alabama
• Doesn't work: http://api.opencivicdata.org/organizations/?name=alabama%20senate
• Works: http://api.opencivicdata.org/organizations/?name=Alabama%20Senate
