SYSTEMPREFERENCE
 
Records changes to the :ref:`system preferences<global-system-preferences-label>`
 
ADD: a new configuration was added
 
DELETE:
 
MODIFY: a system preference was edited, a configuration was added (in the case of :ref:`Automatic item modifications by age<automatic-item-modifications-by-age-label>` for example), records were reindexed
 
Runtime parameters
Parámetros en tiempo de ejecución
**Question**: Is there a way to filter my custom SQL reports before they run?
 
**Answer**: If you want to make your reports easy to reuse with different filters and date ranges, you can add runtime parameters to your query. Runtime parameters basically make a filter appear before the report is run.
Si usted cree que su informe puede consumir demasiados recursos podría considerar el uso de parámetros de ejecución de la consulta. Los parámetros en tiempo de ejecución básicamente hacen que aparezca un filtro antes de que se ejecute el informe con el fin de ahorrar recursos a su sistema.

Scan indexes
Explorar índices:
**Question**: What does 'scan indexes' on the advanced search page mean?
 
**Answer**: When you choose an index, enter a term, click 'scan indexes' and do the search, Koha displays the searched term and the following terms found in this index with the number of corresponding records. That search is not made directly in the catalog, but first in the indexes. It works only for one index at once, and only with no limit on library or library group (All libraries needed).
 
Searching for terms that start with a character
Búsqueda de términos que comienzan con un carácter
**Question**: How do I search for all titles that start with the letter 'C'?
ti,first-in-subfield=C (le mostrará todos los títulos que comienzan con la letra 'C')
**Answer**: You can choose to search for things that start with a character or series of characters by using the CCL 'first-in-subfield'
También puede optar por buscar cosas que comiencen con un carácter o conjunto de caracteres
example: ti,first-in-subfield=C
ejemplo: ti,first-in-subfield=C
Wildcard searching
Búsqueda truncada
**Question**:What is the difference between a keyword search using the '\*' (asterisk) versus a keyword search using the '%' (percent)? Both work in the catalog, but return different sets. Why?
 
**Answer**: A wildcard is a character (\*,?,%,.) that can be used to represent one or more characters in a word. Two of the wildcard characters that can be used in Koha searches are the asterisk ('\*') and the percent sign ('%'). However, these two characters act differently when used in searching.
 
The '\*' is going to force a more exact search of the first few characters you enter prior to the '\*'. The asterisk will allow for an infinite number of characters in the search as long as the first few characters designated by your search remain the same. For example, searching for authors using the term, Smi\*, will return a list that may include Smith, Smithers, Smithfield, Smiley, etc depending on the authors in your database.
 
The '%' will treat the words you enter in the terms of "is like". So a search of Smi% will search for words like Smi. This results in a much more varied results list. For example, a search on Smi% will return a list containing Smothers, Smith, Smelley, Smithfield and many others depending on what is your database.
El '%' tratará las palabras que son ingresadas en términos de "es semejante". Así que una búsqueda bajo Smi% buscará palabras como Smi. Esto se traduce en una lista de resultados mucho más variada. Por ejemplo, una búsqueda bajo Smi% devolverá una lista conteniendo Smothers, Smith, Smelley, Smithfield y muchos otros resultados dependiendo de qué esta en su base de datos.
The bottom line in searching with wildcards: '\*' is more exact while '%' searches for similar terms.
 
Title searching
Búsqueda por títulos
**Question**: Why does my Zebra title search for 'Help' not turn up 'The help' in the first pages of results?
 
**Answer**: In general, the more terms you enter, the better your results will be. Koha doesn't use stop words, so searching for "the" and "an" will work just fine. So "the help" should bring better results than just a title search for help. Also using "Title, phrase" would further improve the results as it means that these terms have to appear in this sequence and with no other terms in between.
 
Some system preferences are known to affect relevancy ranking negatively. These are :ref:`QueryAutoTruncate <QueryAutoTruncate-label>` and :ref:`UseICUStyleQuotes <UseICUStyleQuotes-label>`.
 
Note: If multiple results have the same relevancy score, they will be sorted by biblionumber as second criteria.
