Searching
Zoom To
There are several options available to find properties in HAARGIS. If you want to view a specific area, you can zoom in to a view of a county or a municipality.
 
When you chose to zoom in to a county, a dialog box will open and you can select the county name from the list by using the scroll bar. Alternatively, you can jump to the county name by typing the first several letters in the text box. You can zoom into a municipality by using the same method. By zooming into an area using these two shortcuts, no properties are selected--you must use the "Select" tool or one of the other search methods to view property details in the Results Area.
 

Property Search

Use the options in the Property Search window to search for and to select properties based on specific criteria.
By National Register

To search by National Register (of Historic Places) status, you may first choose the location of the properties--either Statewide, or by County, or Municipality. Select one of the options within the radio button next to it and click the "Next" button. Then you may choose one or more of the formal NRHP standings:

  • Listed in the National Register
  • Part of a National Register Historic District
  • Determined Eligible for the National Register

Click the "Finish" button to perform the search. View the results of the search in the Results Area.

Advanced

The Advanced search can be thought of as a query wizard because it makes searching for properties easy. In the Advanced search, you may only enter one search term per category, but you may enter search terms in several categories at once. In general, the more search terms you enter, the fewer results you will receive.

When you begin the Advanced search wizard, a dialog box opens to let you choose the location of the properties you wish to search for: State, County, or City. Click in the radio button next to your choice and click the "Next" button to continue. The following dialog box shows the first of the three tabbed areas: General, Individual Structure, and National Register Criteria.

Wildcard Search Fields

The fields marked with an asterisk (*) are Wildcard Search fields and set up so that a user can type in a text string (like part of a name, or part of an address) and find the record without having to know the exact way it is entered in the database. For example, if you enter "Park Place" in the Property Name text box, your search will return results like,

  • Lincoln Park, Park Place Cafe
  • Linden Park Place--Belle Avenue Historic District
  • Park Place Historic District
  • Home Park Place.

Wildcard search fields are similar to keyword searches used in Google and other Web search engines, but the entire text string you enter is considered ONE keyword in this application. You will notice in the above example that no records containing only "Park" or only "Place" were returned. Only records in which the text string of "Park Place" appeared were returned.

General Tab

Under the General tab, you can search for a property by its name or address. Many of the properties, however, do not have specific names. Others have several names, some of which are used only on a local level. Unless the property is very well known, a name search may not find the specific property you seek. Searching by address under the General tab refers to the street address. If you are searching for a property in a specific city, the city is indicated on the first page of the wizard.

Also on the General tab, you can specify the NRHP status of the properties you are seeking. If you want to search for properties with specific NRHP criteria, click on the National Register Criteria tab. Note: you must make a selection in National Register Evaluation before you can use any options under the National Register Criteria tab.

Also on the General tab, you can specify the category (building, structure, object, site, or district) of the property you seek, or the survey in which it was inventoried.

Individual Structure Tab

Under the Individual Structure tab, you can search by specific details of individual structures that may appear on a property. A property may have one or more than one structure identified with it--a house, a barn, and a shed, for example. You may specify the architect, builder, or any of the materials that were used for the walls, roof, or foundation. These fields are wildcard search fields, so by entering "wright" in the architect field, you will find the buildings designed by Frank Lloyd Wright and other architects with the same last name. If you wish to enter both first and last names of an architect or builder, enter in the form of lastname, firstname.

You can also specify, by selecting from drop-down lists, the current function of the individual structure, and the historic function, and the architectural style. To find structures by when they were built, enter a year in the Begin Year and End Year text box. You must enter a value in both text boxes--to specify a building that was built in 1870, for example, enter 1870 in BOTH the Begin Year and End Year text boxes.

National Register Criteria Tab

If you want to search for a property on the NRHP by using criteria specific to that program, first select an option under National Register Evaluation on the General tab, then click on the National Register Criteria tab. (These are designations specific to the NRHP program--you may refer to http://www.cr.nps.gov/nr/ for more information.) You may select an owner type, a significance criteria, and a significance criteria consideration from drop-down lists. If you know the National Park Service certification number and/or certification date, you may search by those. You may also enter a significant area, and date range for that significant area (begin year and end year). You may also select a Multiple Property Listing from the drop-down list to see all of the properties listed by a theme (for example, Round Barns in Illinois, Carnegie Libraries, or Historic Fairgrounds in Illinois).

When you have selected all of the options from one or more of the categories, click on the "Finish" button to begin the search. You can see the results in the Results Area.

Query Builder

The Query Builder was designed to allow you to develop complex queries by manually creating search expressions based upon Structured Query Language (SQL). This type of searching may not be for everyone, but we have included the functionality for those who require complex querying. It allows you to search for multiple options within a category (the Advanced search function only allows you to enter one option per category). It also allows you to join search expressions based on the logical operators, AND, OR, and NOT (the Advanced search function links all expressions with the AND operator). Finally, it allows you to change the normal order of precedence by placing parentheses around groups of expressions. Those who are skilled in Boolean searching will find this method of searching very familiar.

The Query Builder screen helps you build queries by a simple series of steps. First, select the field name from the drop-down list of the first category in which you wish to search. When you select a field that has a limited number of options, like Category, you will see a text box appear with a drop-down list for you to choose an option.

Select an option from the list and click on the "Add" button. The statement is then created in the "Where Clause" window:

(Unit.Category = 'building')

If this were the only condition you wanted to use for the search, you could click the "Finish" button to execute the search. However, if you want to add additional search expressions, select a second category from the Field Name list.

Not all fields have a drop-down list from which you can choose a search term. For example, you must enter your own search term into Property Name and Address. Fields that do not have drop-down lists are treated as wildcard searches.

Notice that since this is the second expression, a logical operator is required--the AND operator is chosen by default, but you can select OR if necessary. (When you use the NOT operator, it should be preceded by an AND or an OR.) Click on the "Add" button to add this expression to the end of the existing Where Clause:

(Unit.Category = 'building') And (Property.SignificantName like '%Capitol%')

The wildcard characters and appropriate syntax are entered for you. You may at any time edit the search string that is created by clicking within the box and editing the expression as necessary. NOTE: There are no safeguards against entering illegal SQL syntax; edit these statements carefully.
