Ca utilizator XP, de fiecare data cand aveam nevoie de anumite fisiere stocate prin cine stie ce colturi intunecate ale hard-diskurilor, aveam, implicit, o zi proasta. Si asta pentru ca search-ul integrat in sistem mi-a pus de nenumarate ori rabdarea la incercare, prin modul lent de a afisa rezultatele si, mai ales, pentru ca tipurile de cautari pe care acesta le efectueaza sunt limitate.
Pana am descoperit Indexing Service (Serviciul de Indexare) al Microsoftului, o utilitate care poate efectua cautari de sute de ori mai rapid decat search-ul obisnuit, prin folosirea unui limbaj specific. Indexing Service (prescurtat IS) indexeaza fisierele de pe hard-diskul dvs. (formand asa-zisele cataloage), la o cautare ulterioara, acesta interogand indexul, in loc sa scotoceasca fiecare folder in parte.
IS nu este activat default. Pentru a-l activa mergeti la Start->Search. In fereastra deschisa, dati click pe Change Preferences si selectati With Indexing Service. Daca optiunea With Indexing Service nu este disponibila, in schimb aveti optiunea Without Indexin Service, inseamna ca IS este deja activat.

IS nu va fi disponibil imediat dupa activare. In primul rand, acesta trebuie sa creeze indexul, care dureaza in functie de numarul fisierelor de pe hard-disk si in functie de viteza procesorului. De aceea, cand activati IS, este recomandat sa lasati PC-ul in repaus cateva ore, pentru ca acesta sa poata efectua indexarea.
Limbajul specific al IS foloseste tag-uri (etichete) pentru definirea criteriilor de cautare. Interogarile sunt facute sub forma {prop name=property name} interogare {/prop}, property name insemnand numele proprietatii respective, cum ar fi cele listate in tabelele urmatoare, iar interogarea reprezinta textul pe care il cautati. De exemplu, in cazul in care doriti sa cautati fisiere care au fost reeditate recent de un anumit autor, cum ar fi Stealth Settings, veti face interogarea in urmatorul fel:
{prop name = DocLastAuthor} Stealth Settings {/prop}

Cautarile pot fi efectuate si in functie de frazele continute de fisiere, folosind interogarea {phrase} fraza {/phrase}:
{phrase} Tips and hacks for Windows XP {/phrase}
Pentru a cauta texte, puteti folosi tipul de interogare descris mai sus (phrase) sau interogarea freetext. Diferenta dintre aceste doua consta in faptul ca phrase face cautarea dupa ordinea cuvintelor, adica rezultatele vor include numai fisierele care contin fraza exacta, iar freetext face interogarile dupa fiecare cuvant din fraza, rezultatele fiind mai numeroase, deoarece vor include toate fisierele care contin cel putin un cuvant din fraza respectiva.
IS va ofera posibilitatea sa faceti cautarile si in functie de timpurile si modurile verbelor, prin folosirea de metacaractere cum ar fi dublu asterix (**). Astfel o cautare de genul {prop name=Contents} write** {/prop} va avea ca rezultat toate fisierele care contin formele alternative ale verbului “to write” (a scrie), cum ar fi write, wrote, written.
Concluzie: Recomand folosirea Indexing Service doar de catre utilizatorii care au cunostinte avansate de folosire a sistemului de operare Windows XP. Pentru incepatori este mai simplu de utilizat Search-ul integrat in sistem.
